Oh wow, do I ever hear you here. Especially on the realizing that there's nothing wrong with being this way. It's taken me a long time to figure that out, but I'm so much happier now that I don't feel guilty for not being up for a party (especially when there's only one other person I know there) or hanging out at a noisy, crowded bar. They're just not the kinds of situations I like to interact with people in.
