I tried CBT for my Social Anxiety 10 years ago, and it didn't do anything.

I never really had any friends until my late teens. When I was a kid I didn't socialize. I just stayed at home and played by myself, or I went bike riding.

It's not just me seeking validation from everybody, but specific people. There is a girl I worked with a long time ago and am friends with. I also always had kind of a crush on her too. She reminds me of the hot and popular girl in high school who everyone likes. I was far from popular in HS so the girls wouldn't give the time of day or they would just be snooty with me. Despite that, I always wish I could be accepted by them and maybe get in their circle. That's how I feel with this girl, except she isn't snooty or stuck up. She actually likes me as a friend, though I wish I could get closer in her friendship circle (hanging out, stuff like that). I'm just always afraid of angering or upsetting her in some way that I'll drive her away.

Like I said, I never really learned how to make friends, so I don't really know how to act around certain people.
