Many times I am scared that I am manipulative and when I text someone or say something, I check what I say so I'm not being manipulative

Recently me and my ex partner broke up. We met recently and when he asked me how I was I told him I was suicidal and broke down crying. I told him instantly that obviously the break up hasn’t made me suicidal but the ocd that’s come with it has. I felt so bad that a few days ago I messaged him to say sorry for how much I’ve contacted him and for being such a mess. I asked him if he still wanted to be friends and he said we would but now I can’t stop thinking that maybe he’s just saying that because he knows I’ve been suicidal. I just want this all to stop, I don’t know how to stop thinking about all I did wrong and how much harder I’ve made this break up

hi yall im new here but not new to ocd. for as long as i remember ive had tendencies and ive had compulsions. when i was like 6 i remember counting my steps and that started this life long thing. i get looks in public because ive been touching each side of my face for the past 10 minutes because it “didn’t feel right”. about every one in my life knows i have severe ocd and that’s fine but my grandmother told my mom behind my back one night that i was ‘manipulating’ her and that my ocd could be fake. this is because i can’t take the trash out of the track can because i can’t risk getting sick from old food, i cant use cleaning products on my hands to clean them. i have no probably taking the trash out it’s just removing it from the bin. i can’t do the dishes because its not clean and ill have an anxiety attack because its just simply too overwhelming for my ocd. those aren’t the only things but the list is just too long to write out. but we don’t live with my grandmother anymore. when we did my ocd wasn’t as progressed as it is now and i was able to hide most of my compulsions and “rituals” (what i call them) in private, therefore she doesn’t see how much it can affect my every move. this happened a while ago but i keep thinking about it and i get in my head. when im really struggling it’s hard to not convince myself that i’ve been lying to myself and so many others for 18 years. all my compulsions and intrusive thoughts and the goddamn hallucinations i’ve had from ocd are in fact real but how can my own grandmother call me manipulative like i don’t get it truthfully. i cannot imagine a situation in which someone would go through the trouble of washing their hands 4 times, of blinking 16 times before shutting their phone off. rewriting a whole text to their boyfriend because i misspelt a word and so now the whole text is wrong or any other of these things i and SO MANY people who have ocd or ocd tendencies would go through the trouble because it is SO paralyzing. clearly i’m not going to explain myself to her because i don’t have that energy esspecially if she is going to ‘mhm’ me and then go again behind my back and tell my mom (who fully understands and has tendencies herself and knows i don’t make this stuff up) that im a manipulator.

I am so afraid of developing schizophrenia or completely snapping im always checking to see if im hearing voices or if im seeing things im always making sure that I really heard what I heard from people and not in my head.
