Intrusive thoughts

When an intrusive thought comes I can’t just say “that’s not true” and just move on. I always feel like I have to disprove the thought and be able to say it with confidence but the problem is that the ocd doesn’t allow me to feel and say it with confidence so I get stuck for hours or even days. How can I stop feeling like I need to do this?

I struggle so bad with intrusive thoughts. They can be so bad that I'll cry because I KNOW that's not how I feel or want to do. (Too embarrassed to say what they're about) I'll constantly try to figure out why I have them, and constantly figure out what they mean, causing me to constantly circle around and around. I had to get on anxeity meds, which helped a little but the thoughts still happen. How do you help yourself with this? How do you know that you're just not some physcopath? 😅

Two things are happening: I get thoughts that just keep looping. They almost feel like song stuck in my head. Also, I’ll imagine something and I feel my stomach drop. Then as the seconds go by I keep getting fragments of the this thought but with different details. For example, it’s kinda like how a “vision” is portrayed. I’ll get a glimpse of the thought and then it’ll rapidly expand into something worse every few seconds. I don’t know if I’m causing this or if it’s just an automatic thing like any other intrusive thought. It feels unavoidable, idk if this is a compulsion or if it’s just another manifestation of an intrusive thought. Apart from that remembering an intrusive thought triggers the full thought again and then it just keeps looping or expanding. I don’t know how to stop any of this. Help?
