I dont know anything about meth addiction except what I'v heard, but I'v heard it can cause paranoia, and homicidal thoughts and tendencies, in some people. Which may require medically supervised use of anti-psyhcotic medication. If you dont already have a Psyhco-therapist it may be a good idea to see one about these psyhcotic episodes you'v been having.
I'm like Jules, I worry about you, so please let us know how you are doing, and please contact a professional in psyhcosis, about this.
If you dont want to talk with your regular phycisian about this get a referral to see a Psyhco-therapist. Thats what I did with my bipolar/manic depressive disorder. I'v been seeing a psyhco-therapist for about a year now, and it has really helped me.
Take care, Love, Bonni
