I hate my life! i want to die. Please help me deal with it.

Hi, I am Marissa. I'm so young. I just don't like myself. I'm Italian. So I got a big nose. Everyone makes fun of me. My parents act like they don't love me. So, I thought everyone else's life would be better if I killed myself. I tell you what, I am not crazy, psycho, or not any other thing besides a normal human being. Sometimes, I feel that my cheer-leading coach is more like a mom to me. I mean I love my parents, friends, and everyone out there! So, I want to make their lives better. I just need help with a few things. Please help me! As everyone says, "Depression Hurts."
