Help

Hey guys, I wanted to ask if you have had a similar experience. I am currently in college and usually I get girls numbers whether from the club or in the library (sober). I don't drink. I am usually out going But when it comes to the thought of anything sexual also when she says about smashing another guy, It seems to trigger my anxiety so severely that I get anxiety attacks and I throw up. I have seen that also when it comes to something i see as wrong and that is when I tend to get this anxiety attack. I am writing this here because recently me and this girl we were vibing really really well and sounded like we could start a relationship together. We didn't have sex first time and we only made out. She came also straight to my room. I basically had an anxiety attack at that time. Now when she left she got scared and worried about me and thought it wasn't a good idea for us to talk anymore because she can't deal with it. I always had that fear of having panic attacks resulting in this exact experience. That's why I don't go on dates and now I don't really go for ONS. I have had past truama with girls and I'm guessing that contributed to it in fact that is one of the biggest cause. I have had sex with a couple of girls and they were good looking and in fact one was probably a 10/10. She was the one I lost it to (she had a bf). I felt that was wrong but I was high that's when I lost it so I didn't have a anxiety attack. Now I just have this problem of having these anxiety attacks that seem to put me off and put girls off. Any advice ?
