Mia St. John says there was one reason for such thoughts, and it is directly connected with the mental illness that their late son had. She was better equipped and could handle it somehow, but unfortunately, Kristoff didn’t have a lot of information about the son’s health condition.
He was very depressed and drinking a lot. He could not cope with the guilt that he had of our son’s death. He felt very responsible because our son had schizophrenia and Kristoff was bipolar. … I know he tried desperately to understand mental illness for our son’s sake but he was very frustrated. … I saw the signs in my son so I was better equipped for it. Kristoff didn’t know much about it, which is why he didn’t handle his son’s illness very well. So he blamed himself for his death. Of course, we told him every day it was not his fault. But he just couldn’t live with it.
