To this day i have depersonalization and derealization from psychedelics and anxiety from hard stimulants and my last psychedelic experience is something i would not want to go through again and is the main reason why i have stayed away from those types of drugs. Ecstasy and coke seem to always be around so it is hard to stay away. Psychedelics as well but i have managed to stay away because i am scared, but i have no doubt in my mind that i will indulge in them once again in some point in my life. Once the bad feelings leave. Hopefully they will. Or maybe its better if they dont. Its really terrible though..
Start small with psychedelics and do not overdo it! But the best thing to do is to stay away from drugs completely. Delusions and paranoid thoughts. Derealization, Depersonalization, Psychotic episodes, Traumatic experiences, Depression, Anxiety, Addiktion, Withdrawl, Disappointed and concerned family members and friends and romantic partners, Shame and guilt and the most worst one of them all: decreased sex drive,,, and many more unpleasant physical side effects... You are risking things like this with any drug. Except weed maybe
People need to learn how to be fucking responsible with this type of stuff and maybe some of them if not most them would not be illegal today.
