I think you re right, we all have opinions on things, and some people criticise or judge others and sometimes without even knowing them. I agree with you, that is not right. However, something that is important to I think be aware of is that you cannot control what others might think about you.
I can relate to what you are describing, I used to think (especially in school) that everyone was watching me, that they were criticising me and that hurts! But one day I realised that well, yeah they might be thinking that of me (although I did not know for sure, because actually no one had ever told me anything) but there is no way that I can change what they think and honestly why would I even try, who are they to me? and I also realised that I could not please every single person in the school or else where!
You are saying that you have never heard anyone judging you so there is no evidence that this is happening :)
We also cannot read in people's mind (although sometimes that would be fun :) ) thus if you think someone might be thinking something about you, you have no evidence it is true.
I am not trying to imply that your feelings are not real at all, don't take me wrong :) I am certain that these thoughts really have a negative impact on your well-being and make you feel bad.
However, if people were going at you, and criticising you telling you nasty things causing you distress that would need to be addressed because that is not right.
If I may, I suggest that you have another go with a psychologist and that you address the trust issues with them first so that you can move forwards! No one has to know that you are seeing one. You will not tell anyone if you do not wish to and the psychologist will certainly not say anything to anyone either, just like General practitioners everything that happens in their practice will remain confidential unless you raise issues relating to harm or violence (like I know someone who wants to harm X or Y etc...).
All the best
