>>33281616 (OP)I'd advise against the psilocybin. If your goal is to come back down to Earth and live as a human, psychedelics won't take you there. They bend your perception of reality. You already got enough of that as it is.
Depersonalisation/derealization is caused by consequences, just like everything in life is caused by consequences. You just need to figure out what knocked you into depersonalisation dissociative lalaland.
Depersonalisation/derealization and dissociation in general is a survival mechanic of the brain. As fucked up as it is, as much of a problem as it may seem, it's your brain trying to protect you. From what? That's what you gotta find out. Because when you reach dissociation land, it means your brain turned it on to preserve sanity. As insane as you may think it is, it's actually a mode of the mind that attempts to preserve whatever sanity you got left.
For me that was growing up in a fucked up household in a fucked up family. Which lead me to normalize fucked up behaviours which lead me to befriend and date fucked up people who would routinely emotionally and mentally fuck me up. At some point my mind depersonalised. Because it had to. Because it learned that being 'me' = being in pain. And pain is what was killing me. So the mind turned the circuits off to stop me identifying with life and my sense of self. I went on dissociative autopilot.
Once you figure out what caused you to go into that mode, you can then choose to make your slow crawl away from that old way of life. Then your mind starts to humanise itself again. You can live once more.
Psilocybin cannot show this to you. Only (you) can show that to yourself.
