I truly feel for you & can relate to what your going through. My AS will be 42 in Sept & we are traveling the same road to no where again & again cuz my parents kept enabling him. They say they have stopped now but my AS keeps bothering them and I pray to my HP they don't give in. Helping an addict never does any good. Unless your son & my son make a conscious decision to get well it ain't happening.
Stay strong that really is the only answer.
