hey, I am also interested in learning what medications might help with that sort of thinking. As my mind wonders, and as I grow older, it has occurred to me to stay away from instances, memories, people and places that harbor these sort of thoughts. When I am able to, like when I am alone or have found a way to isolate an intrusive thought, I agree, desensitizing is a useful tool to use. What I am working on for myself is learning how to avoid these situations and knowing what to do when I am faced with something that triggers these thoughts.
