i feel horrible, yesterday i had a class that was 2 hours and 30 min long and the whole time i spent looking for reassurance i couldn’t pay attention i don’t like looking at the girls and when i do it’s to test if i’m attracted but then it backfires idk what to do i give up

I'm in college and about an hour ago i had class. I like to sit alone bc I get a bunch of stupid intrusive harm thoughts. Anyway I couldn't focus AT ALL today. This girl decided to sit next to me and I wanted to ESCAPE. Like i desperately wanted to get up and leave to the bathroom and wait till class was over. I took a deep breath and stayed anyways and tried to focus on lecture but i kept getting so many thoughts and I kept hyperfocusing on my right hand (which was next to her) and my hand felt so weird! Like tingly?? I was like "omg why is my hand feel so weird?? Does that mean i want to do something?!" And it kept imagining me grabbing at her or grabbing my drink and throwing it on her while i was trying to take a sip. I tried eating my breakfast to distract myself but i was holding a fork and got another thought. I realized i was tensing my hands (as a compulsion... i try to keep them as still as possible and as close to me as possible bc the thoughts feel so distressing and the "what if i act out " is playing in my head) And I was internally panicking and now im at the library feeling sad and i feel like I need to solve this. I spent the past hour just mentally reviewing the whole class time rn. The whole class time I was at the edge of the table trying to stay as far as i could and i would get relieved whenever she would stand up to leave the class for something. I managed to make it through the whole class without leaving though but the question in my mind is bothering me so much, "how do I know that these thoughts aren't genuine or are thoughts I want to carry out and why was my hand feeling so weird?" I feel stressed at the library and i want to figure this out 😞

I won’t explain this again if you’ve been or going through it you know what I’m talking about. I felt good about women about an hour ago and now I’m worrying again I’m anxious and the groinals are back and it’s so annoying because I can’t study. And honestly I’m so sick and tired of this. I’ve been a girl crazy my whole life and my mind randomly decides “well what if you are gay” like bro. I’ve never seen a guy that way and in general IT WAS NEVER SOMETHING I THOUGHT ABOUT OR ASSOCIATED MYSELF WITH. IVE NEVER FELT ANYTHING TOWARDS A MAN AND NOW IT FEELS LIKE IT RANDOMLY FLIPPED. I CANT DO THIS BRO. WHY WOULD THIS HAPPEN IVE BEEN GOING THROUGH INSECURITIES ALREADY AND MY ATTRACTION WAS THE ONLY REAL THING I HAD LEFT AND NOW THIS. HOW MUCH DO YOU HATE ME GOD.

So another obsession just popped up and it’s how during school I had a class with this one girl and I would always notice her. Like whenever I looked around my eyes would always go to her. And right now I’m just scared and feel like a terrible boyfriend bc even when something funny happened I would look around but my eyes would find my way to her. Now I feel like I just wanted her to notice me and it feels weird
