People that have overcome/improved depression and or anxiety with drugs, tell me about it.

I occasionally hear stories about people that took psychs or other drugs once of for a short period of time and managed to improve these mental disorders. I'm interested in experimenting myself. I've noticed molly doesn't give me the depression hangover that most people get, I dose low, usually 100mg(I'm 220lb) and roll balls for 5-6 hours then have an afterglow where I feel relaxed and happy for a few days. Shrooms and LSD also make me feel good for up to a week after a trip even though they cause a bit of anxiety during the come up, I've never had a "bad trip" I've had portions of a trip that were uncomfortable but overall every trip was a good experience. Stims make me feel great when I'm high on them but make my mental condition MUCH worse when I crash, I've never done any stims stronger than adderall for this reason.

To give some background I'm in my late 20s, started suffering from anxiety and depression around 23. The anxiety is constant and I'm currently addicted to etizolam, been on it a little over a year, it does a great job of managing my anxiety with no side effects, but if I run out I'm in absolute hell so I've been trying to taper off and get professional help for my anxiety. Depression comes in cycles for me, anywhere from a couple days to several months I just feel awful and don't want to get out of bed, I will sleep for 12+ hours a day if I don't have work, I will avoid social interaction even though it would normally make me happier. I've had suicidal thoughts but never to the point of actually planning it out, I would never kill myself no matter how miserable I am because I know how much it would affect my mom and sister. I'd also like to add that no psychedelics have ever made me feel suicidal so I'm not worried about that. I also make a point of taking them when I'm having a good or fairly decent day and only do them with close friends and family. Usually the worst times are after a stimulant binge when I'm at my absolutely lowest. Since I started having mental issues my longest time completely sober was 8 months, I didn't even smoke weed at the time because I was going for a promotion that would require a drug test. So I know the drugs aren't the cause of my issues, although stims definitely make them worse when I abuse them and benzo withdrawal is 100x worse than my normal anxiety and panic disorder symptoms.
