I don't really have negative intrusive thoughts, but I am on a constant loop of repeating bits of songs, lines from commercials, counting my breathes, running through unimportant imaginary conversations with people who don't matter at all, literally every mundane string of words that I come across,  nonstop, night and day, sometimes even overlapping. It keeps me awake at night and distracts me while driving, and drives me up a wall at work. Listening to the radio doesn't help. The only thing that helps is reading, to a point that I will read a book nonstop for days, foregoing sleep and healthy daily life just to keep my head voice suppressed. I have GAD, and I'm on Citalopram, which has significantly improved the more unpleasant anxiety issues I was facing. But this has been going on my whole life. I just want peace, I want to know what a quiet mind feels like. Maybe I need to meditate. I know it's less when I get better sleep. I can't find much info because it all refers to either negative thoughts or OCD, which I don't really have any other symptoms of, besides the occasional somatic stuff. Anyone have experience or advice to share? Thank you.
