I need some advice with family issues. please.?

Hello, I am 15 years old, and I am a girl. I live in a house with 3 other people. My father, Mother, And a brother(21). I guess i should just get right to the point. Well, I'm a pretty mature 16 year old i like to think, I make good decisions, partially. I do smoke..but i don't participate In any other activities. I'm also very depressed. I have had depression for the past year, and my family hasn't noticed. I am pretty sure my Family does not love me anymore. And it hurts me. Whenever i am home, i get yelled at for everything, even if i haven't done it. My mother tells me everyday to leave her sight, she doesn't want me anymore...She tells me to get a job and move out. I am not her daughter anymore. and she doesnt care what i do with my life because i will never succeed. When i leave, my mom knows that i am going to party's, she doesn't care..She doesn't even care enough to call me and see if i'm okay. She doesn't know my cell phone number..I love my family. I would never say i don't...but why don't they love me..My mom makes me pay for my own clothing, and food. I barely live here anymore. I''m always at my other house where my best friend lives. I don't want to move out, so please don't tell me to. My brother Beat me up the other day and my mom didn't stop it. It was over something really stupid...They are always stealing my money...the only person who cares about me is my father. and he is never home. So my abusive brother is my father figure I cant talk to my dad about it, we dont have that sort of relationship..and i am pretty sure he knows about everything because he often partakes in the ****. I am pretty sure my family never wanted me, and at 16 living with depression, and knowing your mother doesn't love you, is just horrible... I just really want my family to love me again, and know that what they say hurts me really bad. What should i do about all of this?
