My mom always scolds me and says to me that I'm useless. I'm depressed. I all the time cry. Should I die?

I never want or try to hurt her. Even I hide my all pain, my all unwellness, my injuries, my depression and my all tears from her so that it does not make her feel stressed and upset. Even if I'm feeling ill still I don't share with my family because I don't want to see them worried because of me but my mom always scolds me abuse me and compare me with other girls and admire them and tells me that I'm useless. I'm number one in studies and in all extracurricular activities and my whole college admires me and my teachers says about me that my parents are so lucky that they have a great, geniuos and wonderful daughter like me. My mom's those words and behaviors hurts me I never let her feel and realize that she hurts me but I'm really going in depression, all the night I cry and I hurt myself cut myself and I always feel numbed and empty and I've started hate myself so much and I always think about me that I am the worst person ever and worst daughter ever and always hate myself and I've absolutely stopped taking care of myself. I think that I should not exist..
