Drama

I am so sad right now,I'm disappointed at the situation right now.My brother is 23 going on 24 years old and he and I don't get along at all. I know that he hates me,now before anyone says anything,he has told me himself that he hates me and that he would kill me. Now I'm not perfect and I have cussed at him and have threatened to call the cops on him.I have had a part in our arguments but I've never hit him,I couldn't physically do anything to him because he's bigger than me not just in age but height.Honestly the only reason I cuss at him or threaten him is because and I know this might be a pathetic excuse,but I honestly feel like it's my way of defending myself against him. I don't know what do anymore,because I love my brother but I can't get through to him.
