My son now 18 this week we have just noticed severe mental issues talking like it isn't him. He wentwith his friends on a severe drug run and I feel something he did was bad. I have a brother who is schitzophrenic and medicated. Never has and never will work. He is 45. My son has similar symptons but is not severe. He has a loving Christian home. My question is some schitzophrenic activity drug indused or is it something someone has all along?
