I can't say where I would start, i can only say where i did start. It was 1971 i believe, summer before 10th grade. The Mudshark on Zappa's Fillmore East album. I was forever shaped by that song. I laughed at the crazy story and couldn't believe what i was hearing but also utterly transfixed. And i ended up working in music as a lighting designer. Can't say it was that song, but i can't say it wasn't.

You did right, not the least of which is the fact that to get useful therapy that will actually benefit your mental health, your therapist needs to know the full picture. They are very limited in the help they can offer you if you are hiding things.
