Oh OP I’m so sorry you’re feeling like this.
The fact that these anxieties and intrusive thoughts are interfering with your daily activities suggest that this is more than ‘just’ pregnancy hormones. It sounds as though you need some help and support - very common, particularly in pregnancy, and absolutely nothing to be ashamed of. No professional will think any less of you, nor will they assume it will affect how you care for your baby.
When you see your midwife, explain that you’re feeling very anxious to the point where you feel you are not ok. Your midwife will have seen this hundreds of times before and will be able to advise on what to do next.
If your midwife is not helpful (bad eggs in every profession!), don’t give up. Talk to your GP, ask if there’s a perinatal mental health service in your area.
You don’t have to feel like this, your healthcare team can help. I have suffered with anxiety and depression myself and truly, truly empathise with you, it’s horrible.
While you wait for help, try and get out for some exercise once a day. Make sure you’re up, showered and dressed every day. Eat well. Treat yourself - just something small like a face mask, or a bubble bath, or a new houseplant or something! Talk to partner/friends/family. It helps and it lifts some of the pressure off your shoulders. These are all things that felt like huge tasks to me and I didn’t think they’d make a difference, but they really do. (Also medication - sertraline did wonders for me, but this is obviously a choice for you and your doc to make)
In this situation, it’s ok to feel overwhelmed, exhausted and demotivated - that’s the anxiety doing that. The more you can push through, the easier it gets. Don’t be too hard on yourself - take one day at a time, but KEEP ASKING FOR AND ACCEPTING HELP.
You’re going to be ok and you’re definitely not the only person feeling like this. I needed some extra help in my first trimester and my mental health now (28 weeks) is the best it’s been in years.
Sorry again you’re feeling like this - it’s horrible and it feels like such hard work to pull yourself out of it. Let people help you! It will get better xx
