SO OCD support?

Having constant intrusive thoughts is exhausting. They have made me question my relationship, my sexual orientation, if i am a good person, and so much more. It’s weird how they are all connected in a way too. A lot of these thoughts that I have feel so real, and i’m just now learning how to tell the difference between what is true and what is an intrusive thought. but at this point i cannot tell. they all feel real but still make me so uncomfortable. i’m scared i actually feel a certain way, whether that be i don’t actually love my boyfriend, i am actually bisexual or a lesbian, or that i am actually a horrible person and have done horrible things. it’s hard to not believe these things when they are constantly nagging at you. im scared im not with the right person. im scared that im not attracted to him enough, im scared we don’t have enough in common and im scared we don’t think the same way. im scared im supposed to be with someone else and that i am hurting him by lying. and im terrified i am lying about my sexual orientation and using him to deny my true thoughts. im scared i am actually bisexual or lesbian. i think i can accept being bisexual more than being a full blown lesbian, but it’s still scary. im not sure if i am actually bisexual or if i just have intrusive thoughts. and i don’t know what to do from there if i am. if i am bisexual that means to me i have to be with a woman? even though i don’t want to and i’ve never seen myself with a woman. i keep replaying memories with girls and if i showed any signs. and then i get scared that because i was aroused by “specific” porn that it means i am lesbian. all of these things make me feel like a horrible person for treating my boyfriend this way, lying to myself, and for being so confused. it’s exhausting. i don’t even know where to start to get help. im scared that i have had OCD my whole life, and if i have, i’m scared a lot of my feelings and thoughts weren’t even real. im scared when i liked a boy, it was actually my OCD. im scared that when i’ve been attracted to something, it was just my OCD. i don’t know what to do

I think I've struggled with OCD all my life. I struggle with intrusive thoughts alot and recently I just broke down and fell into a spiral I can't get out of. I found out about relationship OCD and sexual orientation OCD and think I may have those. I had an intrusive thought a few months ago that what if i didn't love my fiance anymore and since then I can't shake the idea. Just the day before I told him how much I wanted him to be my husband and up until that point I didn't question my love for him. I don't understand how things can just shake me like that quickly. I know I love him deep down and anytime I get those feelings back my brain is like "you sure about that?" A week later I had a thought about what if I've been a lesbian this whole time and that I'll marry my fiance only to come out as a lesbian in the future. I've always been ok with being Bi, I considered myself 10-20% into women and 80-90% into men. I always had crushes on men and dreamt of finding the man for me one day. I also find women nice to look at but I don't know if it's admiration or actual sexual attraction. Either way I was find with identifying this way but now I'm so stressed that I've actually just wanted to be a lesbian this whole time and that I'm in denail and closeted. These thoughts are debilitating and now I can't look at women without being stressed or getting aroused.

The thing about intrusive thoughts is that I only push them out of my mind when I know that they’re completely outrageous. When I get intrusive thoughts that are more convincing, I want to make sure that the content of the thought doesn’t bother me before I push it out. And this is what sucks because why is my own judgement not enough? I know I’m a lesbian. I know that I never want to be with a man. Why do my thoughts keep telling me “you like men and you know it” and “the only reason you avoid men is because you still like them and you know it” and “if you were to try a man, you’ll like it and you know it. That’s why you avoid them so much”??? Like bye that doesn’t even make sense. But OCD also hates facts bc as soon as I’m like “FACTUALLY, bitch, the fact that I never want to end up with a man or am even having anxiety about liking a hypothetical and what feels like inevitable future with a man is proof that I’m not attracted to them”, my brain just refuses to PROCESS THAT and just TRASHES it? OCD is SCARY.
