Hey everyone. My best friend of 15 years was diagnosed with BPD about 3 years ago. Recently his problems with his family have been escalating, until they kicked him out of the house yesterday. He's been awake for the past 4 days, and I guess they just couldn't handle him anymore. They told everyone he was missing today, and I found him by his favorite bar, raving almost stereotypically about christianity and "I am the messiah" etc etc. I have never, NEVER seen him like this, he's usually very high functioning and very intelligent. He was detained by the police and taken for a 72 hour old to a mental health facility (california).  

I'm lost, this comes out of nowhere, but he's my best and one of my only friends and I want to be there for him but don't know how. When I was trying to talk to him he was giving me the "begone satan" treatment, and I'm worried he won't trust me again, even if rest helps him regain some sanity. I don't know how to help him, or what the path of recovery may look like for him.

I don't know how any of you can help, but any advice or anecdotes you can provide would be very, very appreciated.
