Trouble with dad, yelling.?

Firstly, let me say I admire your strength in being so honest about this. It sounds like you need to establish a boundary. I had this problem too. And for me (as it might be for you) there was no easy solution, except to make some difficult, but worthwhile decisions. When he does something to you that makes you feel threatened, say something like this. "I will not tolerate you treating me like this. If you do not stop I will--" and draw the line on what you will do. A good example would be to tell him that you will leave until he feels like talking to you in a respectful manner. How old are you? If you are 17 or older, I suggest moving out of the house, the reason why is if you live under the headship of this man and he is destroying your personal boundaries, there is nothing you can do to create healthy boundaries because every part of you is legally under his control. (Unless he is physically abusing you.) This sucked for me because my dad was apart of a cult that believes in psychological abuse and he has caused a lot of damage to our family. I know you don't want to leave him, but you need to draw the line somewhere. And if it comes to that, make it clear to him. (Writing a letter works.) That if he continues in this manner and refuses to get help or change, he is also choosing not to have you around, because you will not tolerate that kind of abuse. Then start thinking about what it will require to get out of the situation. For me, I had to find a couple from church to live with and see a therapist for a year before I was able to live on my own. Your story might not be as drastic. I'll say a prayer for you.
