So her family recognized her mental state was in trouble yet she remained out of a hospital in custody of her child? Sounds like the family failed that child.
About 10yrs ago my wife's brother was acting really crazy... after two days we put him into a mental hospital. He was schizophrenic and took 8mos of therapy and drugs for him to stabilize. He still isn't 100%, but he's safe and functional.
Btw, I hate how the OP puts so much on the religion... obviously this has nothing to do with that.
