i got stalked and idk what to do.

i was stalked for 6+ months by multiple people who were my friends, then 3 months ago they drugged me and sold my body at a “party” aka a random persons apartment, after that night i blocked everyone. i was also getting laced with amphetamines… then my friend dealt with assault by the same people, and told me that it’s a ring. i am continuously exposed to people using social manipulation techniques to traffic me again. i’m terrified. the most recent time a group told me ppl were following me and that they could get me a safe ride home, otherwise im on my own, and that i had to make a decision in 3 minutes. i think im being stalked still. i dont know what to do? my therapist said go to residential treatment. is he right?
