I know what you mean about feeling out of place. I have a lot of trouble making friends, too; at least, making the kind of close friends that I can call on the phone just to chat or hang out with on a fairly regular basis. I'm just too shy to initiate that kind of social interaction. It makes me feel a little left out at work (even though I know it's my own fault), because my co-workers--who are wonderful, amazing people--socialize with each other fairly frequently, and I'm almost never involved. It's something that I'm working on, though. I know that no one is going to realize that I want to be involved if I don't say anything, and I'm trying to "come out of my shell" more. It sounds like you're doing the same thing in the chat rooms. Good for you! I've never used the chat rooms, but if I ever do, I will certainly say hi to you!
It can be intimidating, especially for those of us with anxiety and depression, to be involved in a conversation. Keep trying! I promise that there is nothing wrong with you as a person. Have a great night!
