Tread lightly calling a person insane. I have PTSD, Depression and Schizoid Personality Disorder. Admittedly, mental diseases as stated in DSM-IV-TR. But, I am not insane and unlike many using that term, have the papers proving my sanity.

Now the best part. Treatments have much improved in the past 20 years. Unfortunately, too much emphasis is put on to drugs to cure the problems instead of dealing with the problems causing the illness. So your outcome can be happier than your father's.
