Viva anxiety becoming unmanageable

[MyPithyHedgehog]

I have my PhD viva (humanities) later this week. I’m an extremely anxious person at the best of times, but the anxiety I’m feeling at the thought of this flipping viva is more than I can deal with.

I’ve re-read my thesis but all that’s done is hammer home how inadequate it is. It’s at the point where whenever I try to do some prep I just freeze and can’t do it. I’ve tried mind-mapping the core questions but I just can’t articulate anything. What’s my contribution to the field? Can’t explain it. Can you summarise the thesis in a sentence? Nope. What would you do differently? I’d write a better thesis! It’s bringing me really low, and I know that’s not the frame of mind I need to be in going into this. I have very low self-esteem and I never got past the imposter syndrome. In my heart of hearts I just know I don’t deserve it - and if they do pass me it’ll feel like it can’t possibly be worth anything if they’ll let me have it. I know that’s a terrible attitude, and I’ve tried to not feel this way, but I just can’t get past it.

I had a meeting with my supervisors. They offered up all the usual platitudes - we wouldn’t have put you forward for the viva if we didn’t think it was a passable thesis, you’re not going to fail. I don’t feel the thesis was ready to go to viva but this PhD has taken me ages now and I’m wondering whether they’ve just decided to cut their losses and let me fall flat on my face.

I don’t know if I’m looking for advice or just a handhold, really. I just don’t think I’m in a good place to take another rejection right now.

Well given they are leaders in your subject (would be different if they were only tangentially connected) they really ought to know that your thesis was submittable so that should reassure you.

I have only ever known one student fail outright and that was because they submitted too early against all the advice of their supervisors.

You never know - you might find you even enjoy it 😊

I wonder, and others may shout me down for this - still early days in AI and there may be pitfalls here that I don't know about - if it might be helpful to put some of your thesis into an AI programme like the one Adobe has for summarising and interrogating pdfs of journal papers and ask it what are the key findings/conclusions etc or get one of the programmes to produce a PowerPoint type presentation from it? Might that help get your thoughts in order and pull out salient points?

@That70sHouse Oh I’ve been down that road many times, I’m afraid. It just doesn’t work. I’ve never been able to cultivate a kind inner voice or self-forgiveness or anything like that. I really don’t understand where people start. The viva is certainly a trigger rather than the core problem, I’d agree there, but I’m focusing on it because it’s the next obstacle, that’s all. This is how I tend to approach things - always firefighting something! But I’ve resolved to keep things simple once this is over. Like I said before, the rejections are just too much at this point. No point begging for trouble!

@Mytholmroyd I get how that could be useful. I don’t know, I guess I’m a bit of an AI-sceptic. I also sort of think that if it’s truly come to the point where I have to do that for something I’ve written myself that’s probably a genuinely bad sign. I’ll make my bullet points and hope for the best. I appreciate the suggestion, though.

You know, a PhD is essentially a qualification in dogged perseverance which you clearly have! That - alongside putting your head above the parapet - is the hardest part seeing it through to the end.

It's fine if you think you would do it differently if you did it again - lots of PhD students think that - and nothing wrong with saying that in the viva. Far better to be open about what you have learned and self critical - that shows you have gained the required skills of a good researcher.

Everything you describe is exactly how I felt going into my viva. Imposter syndrome, a feeling of detachment from my research and being unable to focus on preparing beforehand. I did get through it though and although I didn’t enjoy it, it wasn’t as bad as I’d built it up to be. Try to be kind to yourself and congratulate yourself for persevering with your project and getting to this stage; it’s a massive achievement! You may find by the end of the week that you are so fed up worrying about it that you just want to get over and done with. The examiners will want you to do well and I’m sure once you get started you will find the words and surprise yourself. You won’t be expected to give a perfect performance so don’t worry about that. Having a rough idea of how to answer the main questions that may crop up, as advised by other posters, is a good idea. If there are areas that you feel are a bit weak, you could think of things that you would have done differently or suggest how you could follow on from your work. Don’t downplay what you’ve accomplished though and try to be positive about your work.
If there’s anything that helps your anxiety put plenty of time aside for that this week. Getting out for daily walks and fresh air helped me a lot. Wishing you all the very best of luck 🍀

OP, You're not alone in feeling this way. The PhD viva is one of the most intense academic experiences, and almost everyone—yes, even those who seem confident—goes through some version of what you're feeling. Anxiety, imposter syndrome, and the sense that your thesis isn't "good enough" are practically universal at this stage. Right now, your brain is in full "catastrophe mode," telling you that your thesis isn’t good enough, your supervisors have set you up to fail, you don’t deserve the PhD, and even if you pass, it won’t mean anything. None of this is objectively true. These are anxiety-driven distortions. Your supervisors wouldn’t have sent you forward unless your work met the required standard. That doesn’t mean it’s perfect—almost no thesis is—but it means it’s good enough to defend.
Your examiners aren’t there to “catch you out” or expose you as a fraud. They want to have an intellectual discussion with you about your work. It’s not a courtroom, and they don’t expect you to be flawless. What they’re really looking for is evidence that you understand your own work, you can think critically about it, and you can place it in the wider academic landscape. Even if you freeze or struggle, that doesn’t mean you fail. The viva is designed to probe and challenge, and it’s perfectly normal to pause, reflect, and even say “I need a moment” before answering.
Instead of trying to summarise your entire thesis in one go (which is overwhelming), break it down into smaller pieces. Write just one sentence for each chapter’s core argument. List a few major ideas in your thesis and how they connect. When thinking about your contribution to the field, don’t aim for a perfect answer—just write down one thing your thesis does that others haven’t done in the same way. These don’t have to be polished; they just have to exist. You’re also not expected to instantly answer every question with perfect clarity. If you need time, say: “That’s a really interesting question. Let me think for a moment.” Or: “I hadn’t considered it from that angle before, but my initial thoughts are…” You can also ask for clarification if needed—this buys you time and shows engagement.
Your anxiety is making you view the examiners as adversaries, but they are more likely to be curious about your ideas than out to attack them. They will challenge you, but that’s not a trap—it’s an opportunity to think critically. If they ask, “What would you do differently?” they’re not expecting you to say, “write a better thesis.” A simple answer like, “With more time, I’d have expanded X section further, or engaged more with Y theorist,” is more than enough. Most people don’t fail outright. If revisions are required, that’s normal—it doesn’t mean you’ve failed, just that your work can be strengthened. It’s also important to plan for the emotional impact of the viva. Even if it goes well, you’ll likely be drained, so make sure you have a comfort plan—a favorite meal, a movie, or just a long nap.
Right now, your anxiety is lying to you. You are not an imposter. You are not undeserving. The PhD process is brutal and draining, but you have reached the final stage because you have done enough. Your job in the viva isn’t to prove that your thesis is perfect—it’s to engage, reflect, and respond. And no matter what happens, you will get through this. All the best!

I agree with all the advice you have received. No one is setting out to trash your work, it's just an academic chat about it. Try and rehearse the most important points. You definitely need to tackle the anxiety. Some say propranolol is good for this, maybe talk to your GP?
Try and visualise the day after your viva. You will be fine.

Once you've done this you can ask AI to provide a list of questions that are likely to come up in viva. It's really useful like this. You can even ask it what to say because you're feeling anxious.

I also wonder about the following scenario.

What if you pass? Will you think they've made a mistake? That they're giving you a doctorate because they felt sorry for you? Or that they were being kind or not as rigorous as they should have been? Will you think that you're not a proper doctor? Or it was a mistake? Or they confused you with someone else? I promise you that when you get your PhD it is because you are worthy of it and you have made a contribution to the field. So don't minimise it when you get it. You have done a tremendous thing.

Let us know how it goes xx

I understand you are catastrophising but allow yourself to spend some time thinking about the worst outcome, which would be major corrections. That would be a real pain, but it wouldn't be one of the possible outcomes for a viva if it didn't happen to a significant amount of people. If that did happen you would deal with it right? This is not a life or death situation. By this time next week it will be something that happened last week.

On the other hand, I'm pretty sure your supervisors wouldn't put you through to your viva if they didn't think you would pass - this would reflect badly on them, and academics generally have quite fragile egos! Good luck :)

Take some beta blockers! Helped me through my driving test.

Thank you all for your really kind and constructive advice. I passed with minor corrections, which needless to say is a far better outcome than I was expecting. I’m still a bit down about the overall quality of the thesis, but I think I just need to accept that it was good enough for two leading figures in my field and that’s enough. The last week or so has been a real learning opportunity, and I think I need to set wheels in motion to pursue therapy again and assess whether my medication is still meeting my needs, because my anxiety and low self-worth are becoming life-limiting and damaging to my health.

Thank you again for all your lovely comments. It’s really life-affirming to know that there are people out there who are willing to spend a little time helping out a stranger in crisis. You’re good people.

Wow!!! Congratulations, Doctor MyPithyHedgehog!!!

Minor corrections??!!

That is a stunning result!

Your thesis has added to the body of knowledge and two leaders in your field think it was brilliant.

I cannot stress enough what an amazing result this is xxx 🪅🥳🥂🎊🎉🎆🍾🏆🥇🏅🥇

Massive congratulations!

Bloody well done Dr Hedgehog 🎉

Congratulations. Excellent news. You've done a great job and it is a big achievement to overcome your fears.

Amazing well done to you mypithyhedgehog!! I felt your pain - brought back all my own viva trauma. Let this success empower you!

Brilliant news @MyPithyHedgehog! Congratulations to you!

Thank you everyone. It is a relief. I find I can now look forward to things that felt aeons away before the viva. It’s a weight off.

Well done, Dr OP! Minor corrections is a great outcome. You should be v proud.

That is excellent news @MyPithyHedgehog many congratulations! Am sure it is a huge weight off your mind. Get those corrections done as soon as you can so it's all done and dusted and you can be free again!

Huge congratulations @MyPithyHedgehog. I’m so pleased for you!

Well done!!

Many congratulations! Minor corrections is an impressive result!
