Can Shrooms really cure depression?

I came to this subreddit after seeing on youtube dozens of videos of science experts talking on TED talks about the shrooms benefits, about how good they are and how they cured depression, I have seen Jordan Peterson saying he could see his DNA and Joe Rogan saying bad trips never exist cause they always makes you a better person. In the comments section of YT everyone ended their illnesses and their addictions, and keep sober after many years. "Shrooms saved my life", I have read that same quote only god knows how many times.

But when I come here I find many testimonials of hellish trips, people using them during years and still fighting with mental illness.

Many say they had very shocking and beautiful experiences, but somehow it seems as soon as they come back to reality they slowly get back to the old mindset or at least they cant fully integrate that valuable lesson. I see some users here realize about how bad addictions as weed affects on their lifes and still struggle to cut it after that.

I dont know, Im just a beginner, but somehow Im feeling a bit pessimistic. Maybe because before I was overexcited as well. Youtube made it look as it was one shot cure solution and I guess it's more like a long and challenging journey.

Any advice to make my journey the most healing possible in the briefest space of time?
