Im scared of my sister and we have a weird relationship?

well i had a brother and one time i yelled at him, scratched him, and talked back to him. he slapped me hard in my head several times and kicked me but i think it was worth it! dont be scared! maybe she has her own problems(friends or relationship)that is giving her stress everyday. and besides, you're really too kind i think maybe sometimes it's good to let it all out because if the feelings inside you gets worse you can be "scarred" for the rest of your life. try confronting her and face your fears!
