I've tried to improve my inner game but something isn't working. I still get afraid when I try to talk to girls I know, let alone girls I don't know, let alone pickup girls I don't know. I still get afraid when I talk to some really confident and 'alpha' guys.

Lots of time what will happen is I'll go ahead and try to talk to a girl, but I still act really reserved, and afraid to crack jokes and express myself. I find that I can really only truly be myself when I'm in a group of friends (not strangers), and not all of the attention is on me.

Why am I so afraid? How do I truly conquer this fear of mine for good?
