I really can't stand my sister. How to not let her bother me?

I hate my older sister she's 21 back home from College and I dislike her as a person. We don't argue often but when we do it's off the meter it takes everything I have not to punch her in the mouth. I'm 20 y/o female we're a year apart but I can't stand her devious ways. They try to say I'm the one with the problem it's because I don't take sh*t talking and I stand up for myself and I'm louder and aggressive that's just how I am, I can't help it. I do not mess with anyone I can sit quite not say a word until somebody starts to mess with me so I don't get why I'm looked at as some kind of bully. When I'm the nicest person to anyone. They think because I'm 5'10 she's 5'2 I push my weight around but if someone talks like a bad a** I expect them to walk like one too (No matter what size they are) "Don't let your mouth write a check yo a** can't cash" people should live by that. How to try to tune her out because I will go to jail for just socking her right in the mouth that's how evil and malicious she is. I can't take it so I need ways since we're going to be home for the rest of the summer together to tune her out.
