Anybody else feel super anxious and scared when playing this game (or heck, any social situation for that matter?)

I feel bad for bringing such weird, personal stuff to the forum like this, but I'm at a bit of a loss with what to do.

I've been playing FFXIV for a few years now on and off, and I've always had such a hard time meeting people and being part of an FC. I feel like no matter where I go, I'm always inadequate, the odd one out in a group. Often times when I try to be a part of things, I always get very nervous and cop out at the last second. It's gotten to the point where I'd leave the FC and stop playing entirely for a while because I'd get so nervous.

I feel like a huge jerk when I let it show like that. I see other people in this game getting along, making friends and all that, and I'd like to experience that as well. Does anybody else feel this way? How do you deal with it?

Thank you for reading, and again, sorry to bring such a weird subject up!
