> but you could also end up in a hellish, confused world of angst and terror for what seems like an eternity, and feel excruciatingly hollow for weeks or months afterwards. The latter can of course be devastating to someone suffering from depression, anxiety or other psychological ailments. Yep, exactly this. I'm about a month past my bad trip, and I'm still dealing with the negative after effects (anxiety, some depression, and occasional DP/DR). I wasn't an overly anxious or depressed person before. I am definitely feeling better than I was a couple weeks ago, and I feel like with more time I'll continue to heal, and get mostly back to normal (although "normal" now means something different to me). People who haven't been there just can't understand the hell that you can potentially go through on high doses of psychedelics. Take the worst experience of your life, then multiply it several times. Now, strip out your ego, and throw yourself into the infinite expanse of space. Then give yourself the absolute surety that you will be in this state for all of eternity. There is no doubt in your mind that you will never escape. That's sort of what it feels like.
