That's all nice and dandy, but with severe mental issues you mention, you both were much more lucky than you clearly realize. Shrooms can do true magic, but can easily drag you to the deepest sewer your mind can come up with, and drown you there. In extreme cases, it can literally break you, sometimes forever. There are people who end up in psychiatric ward for the rest of their lives after single acid trip, sometimes after way too high dose, sometimes not.

There is no way to guarantee the outcome the first time, that's why medical expert supervision is important, especially for people with mental issues/baggage.

That is all being said by person who did shrooms few times, alone, laying with closed eyes and the journey inward and back, with dissolution and later recomposition of every sense and part of my being as a bonus. By far the strongest experience in my life. It was absolutely amazing and beyond positive. But I don't have any mental or childhood issues and am very balanced person who knows himself pretty well (also thanx to these experiences).
