there is a common thread, a mix of alcohol, fear, anger, and separation.

There isn't any simple way to change a life that is on the rocks. Sometimes you can hope for a miracle, a sudden insight that the tormented person can grasp and hold on to, and use to save themselves. But if even the DESIRE to save oneself is weak or missing, all attempts seem futile.

There is one possibility, a direct approach that may work, or may create more angst. And that is to avoid trying to reason with the symptoms, the railings against the co workers, etc, and go right to the central problem.. why is your son so angry? What is it that is eating at him so he throws himself at you and expects you to fix him? Why can't he grasp any awareness of his own condition? Does he do it to punish you? Is there ANYTHING that can give him peace?
