There has been a lot of questions about mental illness lately, and I thought I would give a perspective from someone who has it, me.
I think I've been labeled as having "Schizophrenic like disorder", though it could be something else - so many labels have been tossed around at what I have, it's hard to tell.
Anyway, it causes me to have a learning disorder. This gets complicated because I used to be a genius. What this means today is that I do some things really well, some things not so much. I take medicine that helps my anxiety somehow. But I still experience a fraction of that anxiety. I would actually discourage people from saying "Don't listen to doctors on this subject", because these psychiatrists and psychologists have been to college a lot of years and understand the brain better than us.
I think mental illness isn't directly demon influenced, but demons can still play a small factor I think. The fact is, when you get diagnosed as mentally ill, you should take any medicine prescribed, but you also have to make yourself right with God. I believe that will help heal and soothe you.
I'll give you an example of how demons can play a factor. When I was diagnosed mentally ill, I was drinking alcohol and large levels of caffeine together. I believe demons influenced me to do that. But still, I don't believe mental illness is a matter of "casting demons out of a person". I also think it's dangerous to not be a psychiatrist yet ask people to quit their medicine.
I hope I have given a normal understanding of mental illness from my perspective, and that this thread doesn't violate Terms of Service.
