Need advice, please help

im not diagnosed but for the past five years i've been seeing A LOT of ocd symptoms in myself. i kinda accepted that i might have it and learning about people's experiences helped me a lot. i was in a really bad place when i was 16 but at some point i got better (so i thought) I've lost one relationship and i healed from loosing it and then i fell in love again. we we're together for a year and six months. i was really happy for most of the time but unfortunately we we're both not really stable mentally and we both had some mental issues. i helped my girlfriend and i supported her the best i could. she managed to move in in my city and we started living together november. at first it still was her who had a lot of issues (probably depression and being very suicidal) i was struggling and i was really stressed but i tried my best to help. i think eventually she got better in january everything was happening all at once. i've lost my job and we had to move out to a different apartment and in the same time she gained new friends at work. earlier my ocd was showing up occasionally but since that time i think it got kinda worse. i have very low self esteem and when my girlfriend got really close with one girl in her work i started feeling uneasy. i never wanted to be a jelous and controlling girlfriend but my head was constantly telling me "she's will get bored of you bc of her new friend" "she's starting to care more about her than you" and it was unbearable. we talked about it few times and she tried to reassure me but at some point i saw she's not feeling good about my self doubt and being jelous. months passed and everything was getting worse. she become more and more distant, she stopped showing me any affection, she stopped asking me on a dates, she stopped flirting and even on my birthday i had to please her to stop texting someone and focus on a movie we were watching. and now two days ago she broke up with me. few days earlier we had a serious talk and she told me she doesn't feel like doing anything romantic with me anymore and when i asked why she told me she thinks she got tired of me. i asked her what about me makes her tired and she told me "it's because you can't do and cope with anything" or smth like that (its hard to translate it to English). and i understand that it could be tiring bc i was doing bad mentally and i asked for reassurance a lot even tho i knew it's my compulsion and even tho i told her i will try not to. i am also a very anxious person and i was really stressed aboud my new job and money and a lot of things and all of it made her tired. i feel so guilty that i couldn't try harder. i feel so guilty for not noticing I'm actually loosing her earlier. or maybe i actually was noticing it by being scared when she started to be mkre excited to spend time with her friend rather than me? i don't know i just feel so bad bc i still love her and i don't know if I can't stop bit i already asked her few times if she's sure that this is what she wants and i told her i will try harder and i booked a visit with a psychiatrist but she told me she's too tired to try. im scared she's also struggling mentally. i don't really know what i even want to hear from you guys i just really want to disappear bc i can't stop blaming myself for loosing my soulmate and the best person in the entire world, the most beautiful, funny and sweet person. she doesn't need me anymore. she doesn't want me and it hurts ass hell. and the fact that it might be all my fault hurt even more

i have always been a pretty doubtful and overthinking person all my life, but i have never had bad ocd until something happened in my current relationship i met my boyfriend senior year of highschool, we started off as friends first but then would text all night and found out we have a lot in common, he still lived at his parents house at the time, i'd go over to his or he'd come over to mine sometimes, your typical teen romance story, my rocd didn't start acting up till we started getting serious fast forward to when i started working at my old job and met this guy who pretty much love bombed me, i didn't know it at the time, and so i lost myself during that time trying to balance everyone's feelings, i ended up hurting my current boyfriend really badly and ever since ive had raging rocd, every second of every day i cut this guy off and me and my boyfriend are still together, working it out, and then two christmases ago he gets kicked out of his house, and starts living with me and my family, a huge change i wasn't ready for but it happened my family loves my boyfriend, everyone i've ever introduced him to also does, he truly is an angel, he's so sweet and good to me, i've met all his friends and he's met mine, i could picture a life with him, but currently my rocd is too much to bear, id be better alone but im so deep in this now it's crippling, i can't hangout with my friends without rocd, cant wake up without rocd, cant think of anything without rocd, i cant eat or sleep, life feels like it's no longer real, the relief of breaking up with my boyfriend would free me, but i cant bring myself to, ive tried multiple times, i might just be a coward because i dont want to hurt him again, i dont want to lose him, but ive lost myself, this rocd is driving me insane lets say I break up with my boyfriend, he already got kicked out of his old house and I do not want him to have to feel like he's got to be kicked out again, this is his home now and I just couldn't do that to him, my family would lose someone they see as a son, and I would have to watch him move his stuff which would make me so sad because I care so much for him, I would even move out just so he doesn't have to the thing is I really can't put myself through this anymore, I have to put myself first or this will kill me, idk what to do maybe i could talk to him about how bad my ocd is, tell him that i really have tried to push through but i need a break, maybe we could be friends and work it out? i hope so

I still do not have an OFFICIAL diagnosis (I dont have the means to do so) but given my symptoms, past and present in my life hugely suggest OCD is what I am dealing with. I cannot be 100 percent certain but after searching for answers and researching for a long time now, I am fairly certain and confident this is what I am struggling with. Given this step forward, I am making more effort into giving up compulsions. at the current moment I believe to be dealing with ROCD, as I have been having several intrusive thoughts that conflict with my relationship. For starters, recently over the past month or 2, I have been struggling with intrusive thoughts like not being over my ex, being attracted to someone else, losing feelings for my partner and not being in love, etc. I can consciously identify that I dont believe these thoughts to be true but it causes me so much distress and anxiety. It gets extremely unbearable some days, and I have leaned into 2 main compulsions. I have relied on thought checking and googling as my source of relief. At first the googling was genuinely to start finding answers; hence why I have made some of the discoveries I have about OCD including this site. But it developed into every time I was anxious, I would whip my phone out and start googling strictly to find an answer that would reassure me or calm me down. As for thought checking, it acted as a way to reaffirm my love for my girlfriend in my head when I have had the thoughts that collide with my relationship and how I feel about my girlfriend. It worked at first but developed into a compulsion where every time a bad thought got me worked up id either do my normal googling or Id think about that in my head to calm myself down. Over time these compulsions have gotten less and less affective and now when I do them it only gets me more anxious and desperate for reassurance (strengthening the cycle or whatever it is lol). I did some more research and finally have accepted the very real fact that I am going to have to sit in heavy anxiety and not give into compulsions for a while in order to treat this. I have to sit in the thoughts that make me feel all this hightened anxiety and distress without giving into compulsion. to be honest I am scared, the thoughts are more rampant than ever, but I am ready to commit to this. I dont think I am gonna be able to go cold turkey on my compulsions so I am ready for the reality I might relapse on the compulsions sometimes, But am gonna keep going until I can break these shackles OCD has on my life right now. I wanna ask, what is everyones methods they use to avoid giving into compulsion when the thoughts get loud? any advice is welcome :)
