<human>: Could you distill the essence of the text into 1-3 sentences?

A friend, whom I have not kept in contact with much, is in trouble.  He was homeless, wandering the street, and severely depressed and car jacked a guy with a knife so he could run away.  He stupidly called a friend asking for downers in a moment of panic and turned the car around to go see a friend.  Needless to say he was caught by cops and is now going to court in a week.  We live in Canada BC so i doubt he will get jail time.  However, numerous times he has gone to detox and skipped out early.  I want to make it clear to him he has to go to rehab, and commit, if he wants to ever talk to me again.  He was my best friend and it tears me up inside I don't even trust him in my home.  How do I talk to him without him going over the handle.
