I am being bullied by my 18 year old son. He has major temper tantrums and at 6 ft tall and 180lbs, it isn't a pretty sight. If I ask him to clean up his room, he flies into a rage - swearing, slamming doors, hurling insults. He's always had a bad temper but it seems to be getting worse. I only have peace when he isn't home. He makes it impossible to say "no" to him - like if he wants me to make him a sandwich, I can't tell him to make it himself because then he has a fit. So he bullies me into making his food, giving him money, letting him use my car and so on. I don't want him screaming all the time so I just give in. I don't know what else to do. I wish he would just leave home.
