Hi Robbie-- Have you done much reading on the AV? Addictive Voice? I just learned it here last year and it helped to start separating those "thoughts" from the bigger part of me that wanted to stop the madness. It's taken a long time, but now when the thoughts come up I don't give them my full attention. I have to distract and focus on something else, again and again and again. It takes a lot of practice and planning to keep focusing on other things. I did crafts, cards, 3-D puzzles, read books, watched shows, even when my concentration was only a few minutes here and there. Or memorize a poem, a song. I once learned to sing the alphabet backwards.
My attention got better to focus on other things. The AV still comes but less often and it's much quieter. Recently I rearranged all the furniture in the room that I drank in so it looks and feels different. Keep trying different things and life will become different.
