My sister is a biotch!!!

Ok, so my sister I have to say is the biggest biotch of the family she hates my guts and she is such an instigator(a biotch who likes to start a bunch of bs with one another) she tells me in my face “sorry the devil posessed you” and “ I hope one day you get a freakin machete through your brain” and “I hope you die” and all that kind of bullchunks and it gets really annoying that sleeping on the couch is the only way I can stop hearing her nagging like I do 24-7 she wants everything her way and she throws a fit when she doesn’t I missed her when she waas only two years old…I was four…you know why I was the happy four year old? She didnt talk!!! Me and my sister hardly communicate anymore because the only conversation she can focus on is her fugly boyfriend and when we actually get along, she wants me to see her art you tube videos that only get 3 views and are boring as hell I wish I had my own room back you don’t even know… I tried ignoring but she’d push my buttons even more when she would be ignored. I need some help!!! Advice!!! A guardian angel!!!
