I don't suppose you've got any recommendations for scientific literature that deals with intrusive/obsessive thoughts, do you?

I struggle with this stuff pretty severely (repetitions of phrases like, "you're worthless trash" etc. at <5 minute intervals, all day, every day, for decades). I've been through many years of medication and therapy/mindfulness/etc., and nothing has been even remotely effective on this front.

Dense material is best, but I'll eagerly take anything at all that might be helpful or interesting.
