Sorry to hear about your troubles.
While it's known that psilocybin (for example) can cause lasting effects (never mind the immediate effects for the moment) to a person, specifically, it appears to permanently change people's open-mindedness (literally permanent changes to the FFM character trait 'Openness to experience', which is characterised as 'open to new ideas'), not nearly enough is known about the mechanisms and variability of it's effects.
For every self reported 'cure' there are very likely one or two people unaffected or made far worse.
I agree that the counter-culture that started the whole thing going made it a taboo subject for along time, this has hindered serious study.
On the wiki page on 'Openness to experience'...
https://en.wikipedia.org/wiki/Openness_to_experience
...there's a whole list of personality aspects that are correlated to greater and less degrees with this trait - the problem might be that one's current mental (trait) make-up might be one of the variables (along with dose size) that contribute to overall affects for good or ill.
So, for example, giving a dose of size 'x' to someone already very high in FFM openness (or one of it's facets) might unmoor them form reality, whereas a less open person on the same does might gain a clinical benefit. And so on.
Given that, anecdotally at least, this is (assuming we are dealing with a single active substance) a substance that can cause terrible and lasting permeant affects as well, so I'd suggest that the right thing to so (once the new-age associations are out of the road) is to proceed very carefully and slowly.
I'd add that, it seems only lately have the psychology profession got around to properly acknowledging the difference between pathological mental health, that which is little affect by one's current life situation and 'situational' mental health conditions that would resolve if the sufferer had situational problems resolved (like getting a job, getting over loss etc).
Imagine presenting one of each 'type', outwardly manifesting the similar symptoms, for a clinical trial and giving them the same dose of drug 'x'? Yikes.
