If psychiatry mentions witches cursed our family then it's a curse. If our brain is telling us voices are talking to us through radio or television, we know this not true, because talking voices through television and radio does not exist, because normal healthy people don't hear these voices. You could be talking about subliminal messages. We are regular people in society with an illness. Schizophrenia is caused by genetics, environment and street drugs.

When I hear talking voices through television and radio, I take a break and wait till it's a good time to watch television, because I know it's the schizophrenia doing this. I can watch movies for hours without voices. It will be ok. Keep up with meds, your schedule, your activities, and writing, self help
Good luck
