Help, I think I'm being emotionally abused.

I'm 17 years old. For about 5 years, I have been subjected to verbal/emotional abuse by my father. He had a very rough childhood, so I assume thats why he is so harsh on me. That is no excuse, however. I find myself quite depressed at times, lack self esteem, and I absolutely cannot handle when people yell at me. I'll usually break into tears. This is a few of the many things my father has done:

-When I was about 12, we got dial up internet. I didnt know that when you are online, phone calls can't come through, so he couldnt call us while getting groceries. He came home and screamed at me, calling me a motherf---er.

-I mow my church's yard. I've been doing so for about 4 years, so I have my own little routine. One day my father helped out, and when he saw that I wasnt going in the order HE wanted, he screamed at me. I came home, angered and crying, and when he returned, he yelled at me more.

-He has a grudge against a fellow church member, just because of personal differences. I went to youth group last night, and I had to ride with them because I had no other choice. Upon return, he screamed at me again. Today, he screamed at me more, this time pretty much in my face, and I threatened to take him to court if he didnt stop. He pretty much said bring it on. I told him to stop yelling and he said "or what?".

I'm only 17, so I can't just leave the house. I am in a horrible dilemma though, as my 2 nephews and niece live with us (their mother is a not capable of being a good parent). If I report child abuse, I fear they will be separated (ages 2, 4, 7). What am I supposed to do? I cannot handle any more of this...

Can you contact someone , someone you can trust ?

Honestly I dont know. I live in a small town, so I feel that if I told anyone that it would backfire... What options do I have?

Get the police involved...

What about my niece and nephews though? It'd kill me to know that they would be separated and away from my mother. I feel that whichever option I choose, it would hurt me.

Do they see the abuse going on at all?
It'll hurt... but your hurting now.

They do, but they are too young to understand. I'm just so confused.

There are numbers you can call, websites that could offer you assistance?
