He is at a really low point at his life. He has had to go to a psychiatric center twice (I think thats what it's called) I won't say the specific reason he had to go there twice but it was pretty bad. He has just changed so drastically over the last few months and it has been getting worse. Please pray for him.
Definitely will. I can't speak to every issue, especially knowing so little, but from issues I've had in the past that have been pretty darn severe, being cared about (and shown that care) helps a lot. Being there for him will do a great deal.
