hey! something crazy has happened to my family &amp; we need help and this is a last resort so if you can read this &amp; please try and help 

so, gonna try to keep the long story relatively short. 
my dad is about 53. he’s had a history of severe alcohol addiction my whole life (im 22). he would get extremely mean and abusive when drunk which was all the time. we would see him talking to himself sometimes but if he was sober, he’s a really awesome dude. 

so flashforward to a couple years ago, due to the severe abuse, i went no contact &amp; blocked him on everything. i got married without him, etc. it was hard. 

well, about a year ago i guess he became a Christian. it was normal ish. then about 6 months ago it started to get weird. he wanted to be a christian comedian, which weird but ok. he moved in with his mom and started really wanting to be a preacher/comedy guy for god. which was strange to us but whatever. he seemed normal ish at that time. but it progressively got worse. he got more and more invested. 

he started saying he wasn’t allowed to sleep because of Jesus, he would say he went to bed but mentally god kept him awake. he seemed to describe one night as his “life changing moment” where God came into his body while he was sleeping and his soul raised way above him and then he woke up 5 hours later. since then he has been claiming to be Jesus, claiming to be John the Baptist, really hyping himself up. he said he was the first human modern day army member of Gods army. that his dog was announced and special for God. he kept describing the sleep things (sounds like sleep paralysis?). he just truly thinks he is John the Baptist or something. 
one night a couple nights ago he was up like barely dressed in his yard screaming that the Lord told him he had to pick up all the grass and then attacked his mother when she asked what he was doing. he then ran away; fled for a few days. showed up at my moms house who he’d been divorced from for like 10 years at 4am banging on her door. 
she called 911. he just keeps saying he wants to kill satan and that he is gods general and him and jesus meet face to face and etc etc. 
he was baker actsd because this is the craziest thing ever. he is still at the psych ward. no drugs in system. the doctors are being so slow and we’re getting worried. 
they said potentially bipolar mania but also maybe schizophrenia? they cant figure out what. 

important, they did give him ambilify and at first he refused but they labeled him as incompetent and he was forced to.  they haven’t diagnosed him with anything but we are scared. 

i feel lime i missed so much of my life to my dads alcoholism im just scared to lose another half of his life to something else. 

could this be schizophrenia? what is this? it seemed to come on out if no where.
