I can't handle pressure or anxiety. I choke a good 80% of the time or higher.

I don't get a flight or fight response. I get a freeze response. Then when im stressed, my mind refuses to think of words.It just goes blank.

>having a conversation and some other man puts me on the spot and jokingly says something that makes me nervous
>freeze up and have no response because my mind literally locks up, awkward laugh is most i can manage

or

>girl puts me on the spot trying to flirt with me
>freeze up and fail at responding, my mind locks up and I have no response

It's not like I have things to say, but im too nervous to say them. My mind literally empties, and I have no response.

I feel like i got a fail brain at birth. I used to do drugs, in part to cope with stuff like this. But i quit drugs now. I dont know how to deal with this, when i cant think with out chemicals to assist me.

What causes this /sci/? Is it even fixable?
