How can my neighbor help her son? He's in the depths of depression and his life is falling apart big time.?

He worked a truck driving job nights for a couple of years. The company had him regularly working 10 to 12 hours a night. It was hard work and he would come home exhausted, and sleep all day. He couldn't quit because he had to pay the bills.His wife was very unhappy and left him last spring and moved in with her new boyfriend who lived a block away. She took their 3 kids with her, so early morning he unexpectedly came home to an empty house. He was devastated, though he kept working cause he still had to pay the bills, and the hope was that she'd come back.

Well she didn't. After 4 months her boyfriend threw her out and she was homeless. He did not want her at all anymore, but he did get to have his kids. That was great, but then he couldn't go to work. A sitter was too expensive, since he was working all night and sleeping all day. He's lost his job now, and will be losing his home. For other reason's he'll be losing his license, too.

He is so down he can't make himself do anything he knows he has to do to survive. He's out of money, soon to be out of a home, and even out of a license. He sees no way out and has all but given up. His Mom and Dad are at their wits ends, too, as he is just not functional.

Where can he go for aid with food, housing, and or income. They say he doesn't even make needed phone calls, so he definitely needs help with the depression. Things are such a mess they can't figure out what to do, where to get help, or even the next step to take.

Much thanks for any help you can advise.
