Many psychologists are far screwier than their patients, and have little interest in getting you “better” to a point where you have no discernable mental bugs… that advice might work for some people but I can see it being positively harmful for others, especially in countries where mental health services are provided by the state and can potentially be used to prove you are an unfit parent, or bring stigma in your community.
Psychoanalysis can harm people by crrating egregores of problems that previously didn’t exist.
Going back to the OP, you need a certain amount of mental toughness and personal determination (and a sense of humour) IMO to do magick and not lose the plot, which some people may find harder if they have a pre-existing condition, it;s really down to the person to know if they can handle adding a load of weird shit to their lives.
Magick is innately destabilising because everything people assume as baseline “normality” will start to change, and what’s “real” will start to seem far less certain.
I found magick helped me, and I posted about how in more depth here:
