Oh God yes, everyone is different. Wish I could be like you, but with having social anxiety there's no way I could confront people. I can't go out without my partner, I don't go out with friends, I only visit them at their house and even then they pick me up or my partner takes me there. We all handle things differently, like you can do things differently to me. I agree, I don't think she has anxiety either.
The anxiety I suffer from stops me from doing that. It stops me from doing quite a few things.
