HPPD and .. honestly, some people have bad trips, and while it is popular in psychedelic circles to say "There is no such thing as a bad trip just the way you interpret it" that isn't really true. Even Terrence McKenna stopped taking mushrooms for a decade after a bad experience.
That said, I _do_ recommend mushrooms to everyone I know with depression or anger issues.
I had a panic attack one time, not sure how I should “interpret” that one. I’ve get anxiety since childhood for context. That said I’d love to do a session with a professional rather than by myself. Self medication for mental health issues is a bit of a gamble. I’ve also had good experiences even at higher doses so it’s a bit random
