I am traumatized by people from my past. Help?

Ok so this is going to sound out there. There was this guy (bob) and his group of friends. Bob and his friend used to be wanna be white gang members. They also believed in the occult. Like Quiji boards, demonds, and all that. I was young and VERY influenced by them because I wanted deseperaltey to become "cool". So I hung around them a lot. I was using drigs and alocohol and was becoming like them. I am better now. But Bob's friend. HIS VERY CREEPY FRIEND. Starting liking me and obsessing over me. Telling me wierd and bizzar things. THE NEXT THING I KNOW, BOBS OWN MOTHER, claims to be psychic and talk to demons. Told me that Bob's creepy friend was MY SOULMATE, I ended all ties with these people but still feel unsafe. I never want to see these other people again. Not even on the other side. I need to know the real TRUTH. Help? Should I go to a real psychic or spiritual adviser? Sylvia Brown? Does any one know a good Psychic? I'm scared about this whole situation. Like they brain washed me or something. I need advice on this, or at least some good coping skills. Thank you.
