<human>: We've been broken up since October of last year I guess. And we were together for about a year and 8 months. We had a fine relationship until the end, but nothing I would have an anxiety attack over. 

Tonight, I was driving to my aunt's house (which is in a town I don't go to very often) to pick up a hose. Of course, my ex girlfriend's car is parked in front of some random house that I end up passing by and noticing. She was sitting on the tailgate of a truck with a couple of guys. IMMEDIATELY I start jittering and make my breath much more shallow. Mind's racing.

I've had these before, but they were well within reason. The girl that I was with before her cheated on me several times. I was a virgin, and she was fucking around. There was one guy that really bothered me named John. He was black, and I'm pretty much inferior to everything that he was. I had a really bad outlook on interracial dating for a while because of this.

But now it's not the same. We've been apart, and I'm not in a place to be jealous or anxious over anything she does. She was with a black guy, but I have no evidence that they are together, nor do I care.

Anxiety is the most debilitating thing I have ever experienced. I've learned to cope, but I want to eliminate the cause. I don't want my body to use anxiety as a reflexive response to situations like this. It takes me to places that I wouldn't wish on my worst enemies. But I can't fix it at all.

Can you give me the gist of the text in a nutshell?
<bot>: I get anxiety over my ex girlfriends if/when I see them, and I can't do shit about it. Please help
