My father driving me home from the hospital has a tantrum because we can't dine in at McDonalds. So in turn he decides he will take the longest way home, knowing I would react. Intentional as it was, I fell for the trap. At a stop light my mother gets out , my 8yr old and I follow her. My mother struggling to walk, myself recovering from a mcl tear and Colonoscopy procedure just 45 minutes prior , we are left walking. Thankful, for a strangers generosity to bring us home, I find the car running and him packing his things to leave and drive off. As usual, again another scare tactic. I take the keys and lock the car refusing to give the keys to him. More confrontation, he begins pushing, screaming and cursing at me, all in front of my 8yr old. My parents have lived with me for 7 years. But it has become unhealthy for me and most of all my son. When my fathers antagonistic behavior fails he turns on my son knowing I will defend him. I can escape by walking away from the situation at home, but I don't know how to escape while in a car as a passenger. How do I control my anger?
