If I am being abused as a teen what will happen to my family while pressing charges and after?

I get abused physically and emotionally, I am 16 years old in Pennsylvania and my brother is 10 and my sister is 11. I've recently been through children service center on my own behalf but my parents haven't changed. My mom gets emotionally abused as well and sometimes physically. I want to go to the police this time because it's been going on for far too long, however I always have hit him back but mine was more in self defense. He's a respected man in the community and I feel like everyone will think I'm lying anyways and it will get worse. I'm scared though. I want to tell and get him help and make him be punished so he realizes that's not okay, but I also don't know if it's a good idea, my brother and sister are very sensitive and I think they would be devastated if they lost both of my parents and each other. I want to stay with them wherever we go, I also was hoping I could stay with my mom and just have my dad taken but I'm not sure it'll be that easy since I don't think she's willing to leave him and she knew about the abuse and hasn't said anything. However, I feel like if it is mandatory that we go from both of them could a family member take us until they could get us back or will we never be allowed back? Would we be able to stay together? What type of consequences would my dad be facing? If I get a full time job and I became emancipated would I be able to take my brother and sister? What will happen when I first file the charges? Will I get in trouble too?
