I am very shy. Not as bad as I used to be, but still pretty bad.
My dad was stationed in England when I was a kid. After he and Mom divorced, Mom and I came back to the US. Mom was enrolling me in school, and I was just quietly standing next to her. Mom mentioned that we'd just come back from overseas, and the school secretary said, "Oh! Does she speak English?" I hadn't made a peep the whole time. For a while I was so shy I couldn't order my own food at McDonald's. I was just too afraid to talk to the person behind the counter.
I also have some anxiety problems. If I am in a situation I'm not prepared for, or something goes wrong, I tend to just shut down or have a panic attack. It's better than it used to be, but still there.
The internet and message boards have actually been great for me. The level of anonymity is just enough that I can be social, but still a little detached.
I I fell in love with one of my friends from work, and we got married. He can help with some of the things I can't handle, phone calls, questions in stores, and such. Most of the time I can do things for myself, but there are still some days that I have to "pull in" a bit.
It's interesting, I was reading another thread talking about fun interactions with the characters at the parks, and wishing I could do that. I get up to the characters and can barely squeak out a "hi."
