If you do or don't know about the illness, He has all the hallmark symptoms of it, and in these videos he is in an extreme full blown "Manic State".
By the way, this manic behavior can mimic the symptoms of drug use.
This isn't just about the drugs this is about an illness gone long untreated.
I hope he gets help, gets on the right medications and maybe if he survives this he can speak out on the illness.
