What are everyone’s compulsions like?

At times, my intrusive thoughts get so intense that all I can do is lay frozen in my bed and hope I fall asleep, and usually I do even if I'm not tired. My brain just wears me out and I wanna escape through sleep. (Sadly it doesn't work all the time)

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?

OK, this might sound really dumb, but when you guys get intrusive thoughts, do they just come once and then go away? I’ve heard that repeatedly thinking about an intrusive thought is considered ‘checking,’ but it doesn’t feel like I have any control over how many times it comes up in my head. It’s not like I’m trying to check anything—it just keeps showing up, almost like it’s terrorizing me every time. I can’t seem to stop it from looping, stop remembering it, or prevent it from coming up. Every time it does, I feel horrified, and I already know it’s going to horrify me. I don’t think I’m actively trying to see if my feelings have changed, so is this still considered checking? How do other people get an intrusive thought and just move on? Doesn’t it pop up a million times for them too? I always thought that was normal, but now I’m hearing this could be a compulsion, and I feel really confused, scared, and lost. Is this why my OCD feels so extreme? Because I really don’t feel like I can control how many times the thought pops up.
