My father, who is 86 who has in the past had an outburst of anger without cause is now having these episodes more often. He doesn't like anyone and calls people names but out in the public appears normal and nice, except every once in a while. I am at a loss of how I can help him. He is not religious so he will not talk to my Pastor. He refuses to see Doctors, Counselors, Psychologists, Psychiatrists, and etc.. He sleeps all day long and stays awake all night long. He is a Vietnam Vet. I know that must have affected him but he refuses the company of fellow Vets or anyone. Everything must be done on his terms or he curses and starts screaming. I am absolutely at a loss. Please help!!!
