Can I press charges against a sibling, who has been slandering me to our parents since we were young?

We are both now in our mid-twenties and he has yet to stop. I go to school and he has urged my parents with angry intent to give me the boot non-stop for the past years because I am no longer 18. He gives any possible excuse to legally harm me in anyway so that he doesn't get in trouble. (He used to physically and verbally abuse me as a child, my mother didn't stop him) After I had a bad year, emotionally, at school and came home to relax with my parents, however problems ensued. They placed me in the busy living room day-in and day-out. I couldn't relax and was very agitated and easily provoked to frustration. Whenever I tried talking to them, they would ignore what I said completely and walk away. My feelings were said but never received. Whenever I discussed frustrations with them, they'd walk away or shut their mouth and not talk anymore. This happened for months. This all happened because of the continual angry defamations from my brother. My brother acts in every situation out of anger. His solutions are a result of anger. He pretty much punishes people for anything they do, whether it be a roommate who played a joke, a salesperson who got the information wrong, a bill was misinterpreted by him, etc. All anger and then punishment. I believe that is what my parents have learned from him throughout the years. I haven't been home much because of schooling but now that I came home, everything changed. Everyone acts in anger, instead of understanding, towards me. I strongly believe that this is all a result of my brothers continual defamation. Is there anything legally I can do? I don't live there anymore but I want to press charges for the wrong that was done.
