Hey unguy, I'm so sorry you feel like this - I can't improve on the advice already given but just want to say that you are not alone here.

It's hard feeling like you don't fit in, and isolating can feel like the best way to protect but it perpetuates the feeling - I've been there, it's tough.

I'm so glad you have PC, we are here for you - and many of us appreciate what you have to offer.
