A friend of mine, which sounded exactly like you. Solo trippin to cure himself, multiple times and that it is the best thing ever. At some point he spammed a group chat with weird nonsense until he mentioned that he is going to die and that we should send an ambulance. They found him laying in front of his flat in the snow tripping like hell, lol. That guy is the perfect example, why people shouldn’t do that (alone). I’m not saying people should not do drugs or that psychedelics cannot help to cure depression. It needs a setting, instructions and someone who has experience, can guide you and is sober.
