I know people with chemical imbalances and bi-polar disorder who have to take a certain amount of pills each day so they can get by, but even when they don't take them..the thought of killing themselves doesn't show. They get a little crazy but that's about it...
It's pretty obvious he didn't want to be in jail and him not being on meds lead to the suicide, to me that is still a sign of weakness...
like I said, it's sad and RIP to P.M.
