Yes. In another thread that asked about phobias I said I didn't fear anything, but truly, people scare me. I could rationalize it; other people are the only creatures on this planet that can totally screw my life over. But really, I think I fear rejection, being mocked and bullied, and being misunderstood. All the things I've experienced in the past.
I also have stage fright. The last thing I want is an angry mob chasing me with torches and pitchforks.
But seriously, I freeze up if I think I'm getting expectant attention from lots of people.
I'm very reserved in person and tend to avoid other people when I can. I definitely have some social anxiety.
