How can i start to appreciate life?

I do not feel depressed. I just hate my life really bad. My life sucks horribly. If it was not for my little girl i would just want to die. There is nothing to be happy for other than her, nothing excites me, nothing helps me. I am 21yrs old I've pretty much never had family since 10 and i just want to go but i dont want to hurt my little girl.I know she needs me but geeeeez!!!!!!!!I can never ever ever catch a break, never. And i hate people who act pitiful but today i just can not help it
