Having a panic attack, I could use some insight

Hi, I'm 17,about to be 18. I've been struggling with these thoughts for the past 8 months. I was wondering if someone experienced ever the same because I feel im "different". BACKGROUND: (I'm not diagnosed with Ocd but seeing a local counselor) About 9 months ago I cheated on my boyfriend with this guy S (who blackmailed, manipulated and molested me). Since then when I realized that what i did was very WRONG and so I started ruminating picking apart every single interaction and telling my boyfriend, i tried to remember every single detail because otherwise I felt like i was being a fraud and hiding things to save myself, i had many crisis about it because I had also what i think was false memory ocd. My boyfriend forgave me idk how tbh I still wonder. CURRENT STRUGGLE: Months ago I was sure I didn't wanna S in any way and i was sure even when everything happened. For the past 2 months tho I've been having thoughts like " Do I love S?" "I love S" "S is hot" "Would S find me hot?" "What if I want S?" " What if I don't love my boyfriend enough?" "What if I secretly want S?" "What if I see my boyfriend as a friend only?Do I?" And I tried testing my reaction to intimate scenarios with S, I'm scared I like it i dont really wanna love S or have any secret attraction, I wish I didn't have any of this and I want to be sure of my feelings for my boyfriend because I know I wanna be with him and I see a future with him like he brings me comfort. But a part of me keeps trying to convince me otherwise. Sometimes I think I'd rather die than have these thoughts. Im so scared of not being able to control my feelings, im scared I can't resist S and its giving me anxiety and making me cry. Sometimes when i think of those sexual scenarios with S or I get those thoughts my mind tells me to smile because i like it because I find it funny. It makes me doubt myself all over again. Like I'm always like I need to test if I'd feel aroused to intimate scenarios with S, lately im trying to fight this urge to test and test but my mind is like "just do it this once so you can be sure. I can never watch anything romantic or sexual or whatever because my mind would be like "you and S" or sometimes I'm just enjoying time with my bf and im like " yes we can just have a sneaky cheating thing thats ok" and it makes me want to figure it out to find an answer a solution because idk it just does like I need to find the meaning of it if it means the truth and all. Im worried im just an awful person and these thoughts just ruin my quality of life . Today i had a crisis where i ended up doinf swlf harm, I'm so scared of finding someone that's not my boyfriend desirable or sexual appealing or whatever it is, I also have bodily reactions when I try to imagine and test my reaction to scenarios. Now i keep groing everytime and I dont know why but i have this sensation and I dont want to havebit especially when its something S related. Does someone experience the same thoughts? Am I alone in this? Is this ROCD? What should i do?

I am really worried because I felt confident about my appearance today, then I found myself thrown into imagining if I did certain things like flipping my hair or just looking good around a certain coworker and they'd find it attractive. I don't like that coworker at all and I'm in a happy relationship with my boyfriend, this made me feel awful and I starting feeling disloyal again. I don't know if it's an old habit, a desire for external validation, or what. I can't tell if this was a thought pattern connected to my last post or not. All I know is that I'm really stuck right now. I feel like every time I pick myself back up, I fall right back down again, like there's ice in the road. I can't help but feel like everything I touch or everything I think about crumbles. I feel like my own mind is against me and I don't know who to trust anymore. These small OCD spirals are really messing with my work life, s*x life, everything really, and it's getting to me. I feel with every spiral that I'm getting sucked into a depression again and I don't know what's next. It doesn't matter how small the "bad" thing that "i did" was, but I feel that every little thing is building up to a point and something is going to crash down. I need help. What do I do? Right when everything around me seems to be going up, I feel like I'm being dragged down and I can't do this anymore. Please help me.

Sometimes I catch myself looking at people, specifically men, a little too intently. I feel like I do it to seem prettier or more attractive, but I also think kinda enjoy seeing how they get flustered, I’m not sure. Even though it never goes beyond that, I still feel like I have cheated on my boyfriend, or at the very least, that I am being disrespectful to him. I feel like I’m almost flirting. I don’t know if this is some sort of distortion and or if this is normal. I’m really freaking out to the point where I’m nauseated. Please help. I can’t stop panicking.
