DH.. Who is telling you that you are not good enough and that your problems are worthless and leave me their contact details so I might have a few words with them!!!

You are none of the above!! But you gotta believe it too! And if people are telling you stuff like that they need to be removed.

You have a lot of friends here who don't see any of that in you. Quite the opposite indeed!

Secretum makes a lot of sense.

I think we all have a tendancy to feel like this at times, and more if we feed the thoughts. The people you think that fit right in and others seem drawn to probably also feel like this at times. I do too, I still struggle with not feeling like an imposter trying to be more than garbage. Not near as much as I used to but it tries to creep back in.
