I believe that at least for me, one of the causes of my symptoms was extreme focus on certain aspects of my reality while being completely blind to other parts.

Hallucinogens and empathogens showed me these blind spots, making me a more rounded and open person. It was sometimes extremely pleasant and sometimes so hellish I wished to leave this world. But the hellish experiences were maybe the most effective at getting me to let go of old obsessions and compulsions. I liken it to the difficult coming of age rituals that many tribal cultures subject their teenage boys to to transition them to adulthood.
