wow. I totally understand. Except I am "the mom" instead of the child. I guess how you feel is probably how my son feels. I am sorry your dad is doing these things. I also know you worry about your mom- but please, take care of you- you are young and deserve to enjoy life and not have to worry about your parents all the time.
I understand your rage- I have issues with the rage myself.It is my utter lack of having any control in my life that causes my rage- mabye that is it for you as well.Take care- I will pray for you and your mom.
