It is not for you to save him. He needs professional help and therapy to develop good coping skills. This where it is vital that you lovingly detach. You let him know that you love him unconditionally but that he MUST seek the help he needs. He has no idea what he wants, he is floundering. You must not swim in and try to tread water with him, he'll pull you down. Instead toss in the life preserver (someone who is a professional) and let him swim to shore.
