I didn't know where to put this thread because I don't know what condition this comes under, sorry if this is the wrong section or anything.

So, does anyone else get unwanted ruminating thoughts? Almost like when you have a song stuck in your head; thoughts that go round and round your mind, sometimes they are so bad they even overpower your actual thoughts and you can't focus on anything. This only happens to me occasionally though, and it's been a while since it last happened but I was just wondering what they were and if anyone else gets them?

I don't know if I've explained it well enough but hopefully you get what I mean
