Basically I'm ballsy enough to approach a girl. Sure the AA sucks but sometimes I'll push through it.

What happens though Is that almost all the time I'll just freeze up. My brain just will stop producing words for me to say and I'll just be in this silent state.

I usually am pretty cool and not all that quiet. When it comes to girls though my brain just stops.

I'll give you a scenario that happen last week actually. I was at the mall with my buddy. We were sitting at a table and I see these girls that we had hooked up with like a month ago at a fair. At the fair these girls were drunk AF and basically came onto us. My buddy was a bit apprehensive to go talk to them at first but I talked him into it. We walked around the mall a bit and finally found them and we both approached.

Girl 1: Hey whats up guys!
Girl 2: Hii! (they hug us)
Me: hey!
(freeze up kicks in)
My friend: so, uhh hows it going.
Girl 1: pretty good how bout you guys?
My friend: good
Me: (silent)
My friend: awkwaaarrd
Me: well it's only awkward if you say it is. (At this point I know we fucked up)

We said goodbye and walked away in defeat, even though we already hooked up with these girls.

For some reason these freeze ups always happen to me in the worst of times. I'll be confident, I'll approach then WHAM, I'm my brains function to form sentences becomes paralyzed. I do this a lot and It really is getting annoying.

Anyone else ever had his problem? Any advice for me?

Stop thinking so much and put yourself in the moment. Learn how to talk about anything.

Life in general is easier said then done. You say you "overcome approach anxiety" yet I feel you still have it, it just is delayed and kicks in later. Do you feel you are going to sound stupid when you talk? If you think that, then you will - choose a more dominate frame, stick to that frame. BELIEVE every word you speak is like a God speaking down to his subjects, trust me.

Also think about it like this, you are already far past what you should be; aka you've hooked up with girls, you have talked to them before - so why the fear? You obviously have said the right stuff prior! Realize you aren't going to fuck up all the time and like said before, do not think about it. Remember the 3 second rule, you have 3 seconds to do it, or you already thinking too much and fucked up already.
