Hi cashart. I understand your pain. I really do! Though I realize your hyperfocus on music (and I recall you wrote something about Rod Stewart) is not exactly the same, I went through a period of maladaptive daydreaming that I believe had some similarities to what's going on with you. During that period, I also experienced bouts of dissociative symptoms (depersonalization/derealization and even hallucinations, blackouts, and delusions, to a degree). It was a rough period, but I eventually transitioned out of it.

Please don't let anyone minimize your strife and the intensity of what you are going through. I don't mean that you don't need help. Just the opposite. Just don't let any therapist or psychiatrist laugh it off.
