Feels like it’s sunk in. Please help

I feel so sad, alone, scared and hopeless. Until two months ago there was not even the remote possibility of being anything other than heterosexual and now the idea that I could find out that I was lesbian or bisexual terrifies me to death. Everything was born from the fact that I didn't feel sexual desire towards my ex-boyfriend and I started to be afraid that it was because I was a lesbian... how can I be a lesbian or bisexual if everything was born from this? I would like to run away from myself and my head. I would really like to go back and go back to my life before. I can't take it anymore. I just want to live my life like before

Idk what else to title this. I was watching a film cooper video cuz why not and he mentioned smthn about wall paper customization and icons and stuff and I just kinda had a groinal response followed by the memory of me having my first crush on a woman (my friend at the time) that helped me figure out that I’m bi and I felt kinda intensely for her but that’s cuz a) it was new and b) we were kinda on again off again friends who haven’t spoken in a few years now and I’m over her entirely. It was toxic I think. She was too much like the person who bullied me in elementary school (they were friends as well so my mom made me cut her off which is. Fair. Made me really sad but eh that’s life) I saw her at prom cuz someone brought her. It was nice to see her but yeah that was it. And now I’m mentally comparing what I felt for women in the past (idk intense crush, listening to a lot of gay songs (think she by dodie) dressing semi masc cuz funky, we had nicknames for each other despite not dating or anything) to men (less intense crush but still big crush, I’ve only dated and kissed men so sparks rhere) and now I’m just slightly nauseous and worried that I don’t like men as much as I like women but I think that’s normal for any bi person? To have different levels of attraction to different genders? Idk I feel gross and icky now like I shouldn’t even be thinking about it or her cuz I have a bf. And I do look fondly upon it, now I’m nervous cuz I got more excited about her calling me a specific nickname than I do from my bf calling me honey even at the beginning? Honey felt more traditional and I love it but we do switch around nicknames and it’s always nice, not many butterflies anymore, and sometimes I get anxious when he does lately, if it’s a nickname in Portuguese. Or if he called me a shortened version of my name. What does that mean? I’m nervous now. I was doing half decently today now I’m nauseous again. I’m worried that cuz I liked the nicknames she and I had that means I don’t like the ones my bf and I have and that I just don’t like him or men cuz I’ve been feeling off around him. But I love when he calls me honey, it still feels good when he does it now but no butterflies. Idk what’s wrong with me. Is it even ocd at this point. Even if I do like women slightly more it doesn’t erase that I love my bf. I’m worried I’m leaning too much towards women tho and I’m a lesbian. Idk if my bi cycle is cycling or if I’m just a lesbian entirely cuz I don’t feel much when my bf takes off his shirt, sex feels different, and things feel stale and slow. But maybe that’s cuz I’m checking and comparing. Now I’m anxious fuck. I’m trying not to think about her idk why. I’m worried I still find her attractive or am attracted to her or smthn. She’s in my city. I didn’t care before but now I do. Or if I think about her I’ll think about other women and will only want to have sec with women which not really tbh. I wanna be able to enjoy sec with my bf. It just hasn’t felt right lately cuz I’ve been so depressed and obsessive. I wasn’t obsessing much last night when we had sex but it still didn’t feel passionate. It didn’t feel uncomfortable but I thought it’d be more? Idk. I know it’s normal to not feel him inside me cuz the vagina isn’t very nerved up compared to the clitoris but it felt like more the motions. But tbh. I needed it. Idk I wanted to have sex and it was a nice stress relief. I just didn’t feel butterflies which kinda bummed me out but we’ve been having sex since august so that’s normal. Idk. I haven’t been able to fantasize about sex. The fact that I’m bi makes all of this so confusing. Cuz yes hypothetically I can enjoy the thought of sex with a woman. But I don’t want to rn cuz I’m dating a man. And I can’t fantasize about sex with him cuz I’m getting intrusive thoughts about my friends and I having sex. I have this urge to watch porn cuz it’s been a while but I’m not going to. I’ve cut down a lot on masturbation. Partially cuz this partially cuz I wanna do things with my bf (when I’m mentally ok) but jow my brain is saying “Oo you think all these women are so hot you’re gonna go feral blah blah blah” and yes women are hot but I don’t wanna have sex with a woman. Idk saying women are hot doesn’t bring me anxiety but the thought of sex with one or leaving my bf and saying I’m a lesbian bother me. Cuz I know it’s not true. I love him I know that. I’d be happy if we stayed together. I wouldn’t regret a thing honestly. I like having sex with him. Idc if it’s not like porn or the movies. As long as I’m being pleasured and he’s being pleasured we’re good. That’s what sex is about. I think the loss of butterflies is normal cuz the excitement of like (sorry tmi) fingering and oral eventually wears off right? But still feels good. I don’t feel as excited about intimacy anymore cuz we have done it so often but it still feels nice. But my brain perceives that as me not liking sex with men and therefore I’m gay. No I just don’t feel the need to jump his bones every single time I see him?? Idk the friend thing is bothering me. Idk if I feel any joy behind it. The groinal response really really throws my perception off

These past few days I was fine. Minimal intrusive thoughts ,no anxiety etc(to add I'm on medication so maybe it's starting to work although it barely is 2 weeks) and today I got a sudden wave of anxiety and it started latching on some thoughts like" what if I'm in denial and I wanna break up with my bf? And what if erp doesn't work for me because I actually wanna break up with my bf?" But they didn't really stay long usually those thoughts would make me spiral for days or so, now they lasted for some hours. And now I'm trying to trigger myself into being anxious again because if I don't it means I don't have ocd and if I don't have ocd it means I don't love my bf and if I don't love my bf it means I have to break up. Idk if it makes sense but the lack of anxiety makes me wonder if I actually have ocd or not.
