kfb -“Should I even try to help my poor friend?”
This must be very emotional for you, but before you invest time you must have a game plan. There are many issues going on with your friend. Does he even respect your opinion? Do you have any way to help him with his family problems? More likely than not, by the time he got to this stage, it’s too late. Can you get him into see s/o who deals with OTD people? Speak to an Odom Godol before you do anything.
