I had been wondering how things with your brother had been going. I'm sorry to hear about the house but I think that was inevitable wasn't it?
Its great that he has such a support in you. I hope that all of this now makes him want to get some help and start to sort his life out. You can only do so much remember that and as much as you want to help him, he has to want to help himself.
I hope things start to get better and he decided whether or not he's going to live with you. It might be a good solution for the short term until he gets some help.
Take care and hope you aren't too stressed out with all of this going on. It must be hard on you too.
Post here anytime and let us know how things are with you.
