Imposter Syndrome

[FluffyDucky]

Does anyone know if imposter syndrome can be diagnosed, and if so who through?
I felt felt for a long time like a fraud, I have depression too so am constantly beating myself up anyway, but in the job I am in I honestly feel like at any moment, someone is going to realise I'm shit at it and I'll get fired.
In theory, I'm not shit at it. I work on a cosmetics counter/skincare and my store is one of the only in the region to be in profit year to date (and the highest) but to me, that is pure luck and a fluke. So in my mind, I'm a failure and a fraud for being there while sales are going through. I've recently been asked to do makeup privately for a company who will be doing professional videos online. Again, I think they are soon going to realise they have asked the wrong and that what I do is really shit. My manager wants me to do like a group makeup session (so if someone is happy to be watched, other watch while I apply and explain), but I am so terrified someone will go 'she's talking shit!'
I think this is a mixture of lack of self-belief and confidence, but I really really feel like a fraud!
I'm sorry if that was a bit long and disjointed (I tend just to write when it's in there lol) Does anyone have any advice or experience?

Bump for evening mnetters

Wow, I've never heard of imposter syndrome before, but your post rings so true for me. I live with a constant, sometimes overwhelming, dread of clients, colleagues, my family, DH, everyone suddenly realising that I'm a complete fraud and I haven't a clue what I'm doing or how I got here. I can't offer any help or advice, I'm sorry, but I hope someone can.

I had a psychotherapy client that had very similar feelings about herself as you have described. She came to me for other issues but it soon became clear that the feelings that you have posted about was in fact her underlying issue. We did a LOT of work on why she felt like this (her history/child years) and how it effected her daily life now. I worked with her in a intergrative style, analytically for about a year then more cognitively for the last few months, this enabled her to gain insight and understanding then 'action plan' for how she could counteract any slid back in the future.

I received a letter two years on from the end of her therapy saying that her whole life had improved and that she was still doing very well.

I feel that counselling could help you in this way too?

Many people seek help with problems like this to varying degrees. Often there is no need to 'diagnose' the problem, it is better to start and then work through it.
Get some help in the form of a talking therapy. I hope you feel more secure soon, often this sort of problem can start to reduce quickly once you are in therapy..there very definitely is steadier ground nearby
