Life

Hey guys, I'm new to this I'm just a person who does not really understand her life sometimes. Have you ever wondered why was I put on this earth at all, why did God create me.Im sorry if this sounds corny but you are the most important person and you serve a purpose in this world. When I was in 8th grade I thought it was okay to cut myself because I served no purpose in this world. I felt my mother didn't love me she loved my god sister more. My mom did everything with her that she never did with me. Im a girl and what I'm about to type you are going to think she is just s girl she can't do these things. Well basketball, football, and track helped me keep my mind off those kinds of things of people not loving me. My parents used to tell me that I'm stupid and I will never get any where in life that I'm worthless (only when they are mad at me), but still it really hurts me that the think this. Me being short (I'm 5'3) people used to make fun of me when I was younger for being the smallest kid in my class and all those years bought me to cutting myself. Even though I just started this its one thing to hurt yourself for stupid reasons, but its another when you don't feel loved or is going through something life is a precious gift that we should always treasure forever.
