I finally realised that my problem is my inner game..

I literally just went out with a friend and a girl (and her friends) I had done stuff with but not had sex with (who is legit amazingly hot). From the start she is really into me and but I am just completely stuck in my head, cannot speak, feel incredibly awkward and spend the whole eve pretty much in silence...

I've never felt like such an afc in my life. At one point I had to speak with her so I came out with "how have you been! she said good! you? I said good and then just looked away...

This has made me feel so down - why can't I fix my inner game? How do I develop true inner confidence? I feel like I am not a real person
