Hi and welcome!!!
I dont know what kind of recovery program that youre Mom went to.,that they said she couldnt be helped.But in Al-anon we are never[although some will,lol} to tell another to leave,or not to leave.Its all about ones own recovery.Working the 12 steps,in order to make clearer decisions for ourselves.I cant say enough good things about Al-anon.its one great recovery program!!!!
