I can't take it anymore.

Ever since my dad passed away my life has been a living *** hole. My mom stays depressed, my sister has become a bully, and my little sister relies on me so much. Today I accidentally lashed out and told my sister I hated my life. And she called me stupid and that I have it easy. I just can't take the fact that no one in my family cares about me anymore. If I'm not cleaning, my mom gets mad at me. And when I ask for help my sister gets mad at me. I'm having to raise a child alone it feels like. Why does no one get me. Why does no one feel bothered enough to help me. Why. What did I ever do to deserve this. I just want life to be enjoyable again.

And yes I've tried talking to my mother, but last time I told her I can't take it anymore she got mad at me because she thought I meant suicide. But she doesn't listen to me. No one does.
