I used to have the feeling with an MBTI-based forum. Everyone there had the same feelings towards normal people and many had problems with shyness. I lost the feeling of belonging though. Everyone there just seemed so different to each other, and I didn't think I was like any of them.
I think this site is kind of the same. It's only really this one thing that connects us.
I should add that I felt absolutely great when I stopped posting on that other forum. I'm my own person. Here, it's just a place to discuss social anxiety.
