I didn't need mushrooms. I needed therapy, friends, a social life, a sex life, goals, something to look forward to in the real world.
All I found on mushrooms at the time were horrible existential loops that just made things more hopeless. I would read about people having these peak wonderful experiences or Mckenna alien experiences and just get more depressed that even the mushrooms didn't help me.
It is almost blasphemous in this space to say what actually ended up changing my life were SSRIs. A little prozac fixed something that was just chemically wrong in my head.
What seems obvious is there is enormous variability in people's brain chemistry so the tool to fix the problem has to be quite specific for the individual.
Your own internal processing will still determine how you perceive a perspective change, but specific to this idea in particular, you may for example, within, suddenly find it obvious to think of things as being made of something different than in the outside world reality (and this sort of "change of bases" may reveal some kind of truth not otherwise visible.) You may see something as formed of language instead of molecules and atoms, or vice-versa.
