Songs stuck in your head

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?

When you get a stuck thought in your mind, as stupid or untrue as it may be, how do any of you block them out, or try to at least? It’s like my mind has another voice telling me making up the stupidest things?

I’m curious how many other people experience this! I’ve been diagnosed with severe OCD for 20 years now, about 10 years ago my little OCD brain came up with a series of words. It is saying everyone in my families name and then something negative, and then something positive. Since my brain attached to this series of words, it hasn’t stopped repeating in my mind. Like I said, it’s been 10 years, and this “phrase” is constantly repeating over and over in my head. When it’s finished, it just restarts again. My brain is constantly exhausted since it’s always talking. It’s kinda hard to word this so idk if it’ll make sense to you but let me know if this is something that you might experience as well!
