I'm losing my mind

Background: I'm 17 about to be 18. I cheated on my boyfriend with this guy S( which I now cut contact with) months and months ago, I came clean to my boyfriend and he forgave me but that's when this all started. I'm not diagnosed with Ocd yet but jm seeing a local counselor. Now: In the past months I've been having thoughts like " what if I love S" "What if my boyfriend is just a friend to me" "I'd rather S did that * insert sexual thing or normal romantic thing*" " S wouldn't do that" "What if I secretly love S" "I love S" and I kept imagining scenarios with S to test how I'd react physically. These thoughts are there everyday for me 24/7, some days it's worse some it's better but I cry about them everyday because they build up and I just explode. I don't want to have them but they get worse and worse with time and I'm scared they reflect some kind of truth because of my past. I finished to have a crisis now, lasted at least 1 hour and I cried my heart out, my mind was like " I dont want anyone else to touch me like my boyfriend does" but then it said back " I love S" " I want S to do that" ecc ecc, got so bad I need to refocus during sex and I need to see my boyfriends face to be sure it's him because I'm scared S is gonna come into my mind and I'm gonna get turned on for him thing that scares me to death. I had the same with pedo like thoughts, for a while I had to avoid children because I was convinced I was a pedo. This comes and goes but the theme it's most in my mind it's this S theme around my relationship. I love my boyfriend and I don't want any of this, can someone please suggest me what to do?

So pretty much I’ve been dealing with intrusive thoughts my entire life, I had no idea could’ve been symptom of OCD until maybe a year ago , I have this fear right now that I don’t actually love my fiancé and I’m not attracted to men. I am attracted to men. Let me be clear. I’m not attracted to females. I never have been and I never will be. But it’s one of the scariest thoughts I’ve ever had that I don’t actually care about the person that I would sacrifice anything for that I would do anything for. He’s pretty much the closest family that I have and I just wanna be with him for the rest of my life. A couple months ago was that I just didn’t care at all, and I didn’t have any feelings and everything that I felt was me being fake in that nothing was real. But I eventually got over that and the new thought is that I’m actually gay even though I know I’m not. And in the world we live in now where it’s be yourself be you if it comes across your mind. That’s the obvious truth. Be yourself… It’s kind of scary to think about. I just want it to leave me alone. I’m actually so scared that eventually I’ll believe it because some thoughts that I’ve learned were intrusive. I ended up starting to believe and it turned into a whole catastrophe for my life. I met this girl and she felt a certain way about her husband and then she told me that eventually I’ll feel that way and ever since then I just I haven’t gotten over this fear that I’m gonna end up feeling the same way she is. Also, I recently got over a few themes. I’m not ready to share, but I’m so proud that I got over those and I just I’m waiting for this one to leave me alone and it’s not and I’m starting to get really scared that it’s true and I don’t want it to be true. and just to be very clear I don’t care who you love what you love who you like what you identify as because you can in fact be yourself but this just doesn’t feel like me. I’m genuinely reaching out to try to get help for this because now it’s messing with our personal life. We’ve never argued so much in our entire relationship and now I realize that it’s mainly my fault because I’m detaching myself from all emotion just so that I can get over this thought I’m detaching myself from all intimacy and that’s even scarier because what if it’s not me detaching myself and it’s me just not being attracted that’s another thought I’ve hadI’ve gone all long enough so thanks.

I am at the point where I feel like I don’t even know myself anymore and have a really hard time explaining my thoughts and feelings. The thought that no one may ever be able to help me or understand me is blazing constant in my head. I don’t know if I will truly ever be happy, the dissatisfaction I have in my life is beyond words and I try to be happy but my mind is so toxic and ungrateful. I feel that I may never understand myself. Have been dealing with extreme intrusive thoughts in regards to my relationship, if my partner is for me, if I am the reason problems come up in my relationship, if I am overly sensitive causing arguments etc. I will have constant thoughts about other people in my head although I have a partner. A hyperactive imagination of others if you will or specific individuals in my life. I have a severely low sex drive. I have also noticed recently that my partner will say things that I don’t like but can’t tell if he’s the problem or if i’m the problem. If I like my partner anymore or if I don’t, can I see him in my future or not. When I am with him I enjoy being with him but there is always a thought in the back of my head of do I just like being around him as a friend because I am lonely or if I truly love them. It’s to the point where I question leaving them or not. My only issue is that I don’t want to leave but at the same time I have trouble feeling emotionally and sexually connected. I even pick at physical imperfections that they may have which to my true beliefs does not matter I will love them otherwise. We recently have been arguing a lot and I can’t tell if I am the problem or he is but it causes me a lot of stress because I feel misunderstood and feel like he wouldn’t understand me unless he was me. It can be hard explaining OCD to him because he is one of those people who loves to self help almost like a life coach, explains to me that anxiety doesn’t exist and that I can help myself or stuff along those lines. It hurts so bad because he doesn’t understand how hard it is for someone with OCD and how him saying things like that only makes it worse and makes me want to turn away from him in a way. I want to feel like I can talk to my partner and that I know for a fact is my true belief. I pray that God will heal me of this terrible disease. I feel I have turned away from the Lord so much because of how alone and misunderstood I feel with what feels like no change. When I’m in public I’ll look at a guy and feel as though because they looked at me back they will think I like them or that I may be interested even though i’m not. I obsess in my head sometimes about real people I know that are kit my partner and have just learned to accept that but it’s still disheartening to me. I understand the concept of being with a partner and still finding other people attractive without obviously doing anything about it and I try to remind myself of that. Please someone tell me this is OCD because the thought of it not is sickening. Another thing I do is compare myself to other girls my age almost that if i’m not as pretty as them im not pretty at all. To whom ever reads this please be very mindful of how you respond because I am triggered very easily. But I am so so lost.
