honestly...i dont know about anyone else but it seems pretty easy to tell you what it probably is. drugs do tend to mess up the brain...it probably is the heavy drug use, they are unwanted substances that your brain is trying to handle, that your body is trying to handle. I strongly suggest you find a drug rehab program along with a therapist. I would also suggest you talk to your doctor about looking into the affects the drugs also have done. Remember, I am not a doctor so you really should find someone qualified to diagnosis yourself. But i strongly urge you to quit the drugs...they really do mess up alot thingsin us. Its not healthy.Please find some help and i hope you get answers. Good luck and take care. Love, Inny
