Is something wrong with me?

My parents are away overseas at the moment and my Grandmother has been sleeping over by our house for a week, she still supposed to sleep over for another week. I'm a middle child and I'm so sick of my older sister. She's supposed to be doing her exams but I've literally become the domestic. She's supposed to be studying but she's always hanging out with my grandma watching late night shows and she's always laughing at their inside jokes. I feel compliments left out. I slept by grandmother's house because she gets scared when she's alone and I could finally open up to her about some stuff. My older sister never keeps her mouth shut, whatever I tell her not to say she goes ahead and throws me under the bus. It's actually my fault for opening up to her. My sister has such a fake personality she can just fake laugh through everything. She sounds like laugh track during a friend's episode. I miss my parents more specifically my mom. Sometimes I just want to lock myself in a room and never come out.
