I started having horrible anxiety around the holidays. I had some panic attacks, I had an irrational fear that the devil was going to possess me or had possessed me. What would cause this irrational fear. This lead to sleepless nights for 4 nights. I went to the doctor. He put me on lexapro and klonopin. I felt better in a couple of days. Lately, the lexapro has been making me very tired and I have had trouble sleeping. I tried to not take the klonopin because my doctor wanted me to try and take only the lexapro. I went back to the doctor today and the nurse pract gave me a scrip for wellbutrin xl 150mg to take with the lexapro bc of the fatigue and weight gain and klonopin to take when needed if i cant sleep. When I start to drift off to sleep, my head jerks or my arms and legs jerk. This has been going on for a couple of weeks. The thing is, is that I have freaked myself out about demon possession and I am afraid that a demon is trying to take over. Is this a sign of schizophrenia or is it just plain horrible anxiety? Any help I would appreciate.
