We all go thru hard times and what your son needs to do is have a long talk with God about everything, for God can take it. God can take your sons anger, sadness, and disappointments etc. etc. Your son needs to have it out with God and it will cleanse his soul. God loves him immensely and will gladly carry your son's garbage bag for him. So tell your son to picture a big green garbage bag that the Lord is holding open for him and to start filling it up with any junk he has and then hand it over to Jesus to take care of it for him. For Jesus bears our burdens and carries our sorrows for us.
