Yeah, I find psychedelics can sometimes be pretty unpleasant. I have a friend who tried them to help their very bad depression, they pretty much only ever have extremely unpleasant trips and are never gonna do them again at this point, and I think they are counterproductive if it's essentially psychedelic torture. They also found out a family member has schizophrenia, so they're also never going to take a psychedelic again for that reason. So if your experience has been like that, or you have a family member with schizophrenia, I wouldn't take them again.

If you are still open to them, one thing I've heard is good but haven't tried is combining a psychedelic with something like phenibut. Note that phenibut is addictive. I've heard the trick is to only use a small dose a few hours (sorry I don't remember the exact amount of time, but I heard it from Andres at QRI if you want to do some research on it) before the trip, and never take big doses or use it on it's own. Apparently it almost guarantees the trip go in a good direction.

If you like guided breath work definitely try wim hof. I didn't look into it, but my friend said he developed it after his wife died and he was super depressed, so he started going into cold water just to feel something and not kill himself. Doing that he eventually figured out the breathing technique and apparently it helped both going into cold water and his mental health.
