Sad !!!!!

My family sucks. My sister got mad at me and told me to kill myself. My mom she either ignores me or tells me I'm worthless or to fuck myself or in pathetic or how I ruin their life just by Begin alive. My 2 older sisters left to go live with my  cousins cause they hate our mom and so do I. My mom wonders why they left but it's because she treats us so badly. I wish I could live with my sisters. Sometimes I actually think about killing myself then maybe my family would be happy since they treat me like shit anyways. I just don't know what to do. Sometimes I think I'm depressed. Am I?
