Skipping classes is so addicting once you start. Don’t do it. Even out of anxiety. It’ll just increase more

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’ve noticed that I’m somewhat happier also ignoring my thoughts than I am instead of doing compulsions (I’m sick and tired of being sick and tired atp) but I’ve heard you’re technically supposed to do erp rather than pushing under the rug. But idk if I have a thought I just refuse to think about it again and im fine even if I want to do compulsions

So maybe the title wasn't the best to to put it but when you guys start having obsessive thoughts how do you stop them before it turns into compulsions and anxiety?
