I am so anxious

Guys I need help. I feel so alone . Basically I have this compulsion where I feel the need to write everything but this stems from me being anxious about EVERYTHING. Like my mom came in my room and I was irritated and snapped, immediately regretted now I keep writing “don’t be mean to mom next time” but I keep thinking about it. Then I think about how I finally left my house today and all the surfaces I touched that could’ve been contaminated and now I’m writing “next time don’t touch this and this”. Then I think about all the things I need to be doing for this week and I’m writing “don’t forget to do this and this” even though I’ve written it 5 times already. This is what happens everyday btw. My brain always thinks about something I need to be doing and making me anxious that I’ll forget it which is why I write it down on my notes app. I’m sooo mentally exhausted I need help pls!! Anyone have any advice ? I used to think I need to stop the writing but really I need to stop the anxious thoughts coming into my head . People say I need to accept the thoughts and let it go but that’s too hard for me

I’m on my period and o think my ocd feels a little worse today… I feel anxious and like something bad is about to happen, like I can’t move or talk cause I’ll freak out or snap and do something. Also I had a gronial response about an SA topic and I feel horrible, I’ve noticed that I do have these gronials as if I’m actually into that but idk if it can happen that you have the gronial and think “oh I’m horny, not about this but I am” is that possible? Idk how to say it… also I think I just want reassurance but I’m also scared…

I’m anxious about HIV. What if I get it? That’s a scary thought to me. And then I’m scared/worried about giving it to others, not knowing if I have it, etc.
