Do I go to heaven if I have schizophrenia and skip hell?if not does it say anything in religion (I mainly talk about Islam but other religion is fine.

There is no such thing as Hell or Heaven. It was created by zealots to keep you in line. The sun will shine irrelevant as to who you are. If you are scared it is very easy to manipulate you hence the fear of god and punishment. Islam is a cut and paste religion borrowed from other religions which applies easily to ignorants.

I think Heaven and Hell both exist.

I'm not sure whether or how schizophrenia contributes to either destination.
