Re: Family situations that you can't help with
Take brother 1 out. Try to network with your woman to help him out. Even if he doesn't find someone right away, I think it will help with the healing process. Try to get him to move forward and see himself with another woman. You said he is a homebody, so you will have to talk him into doing a group date most likely. Go to a Reds game and out to eat, something like that.
As for brother two, I'm not sure if he will be able to get some kind of insurance or government aid to help pay. Let him know he can stay with you or find someone willing to take him in and that it is completely fine that way his worries will settle a little. KoryMacs advice is good about getting their minds off of their problems. I think just talking to them every day for a good period of time will do wonders. Make sure they know you will always be there. Not much else you can do.
Good luck and hope everything works out for them.
