My so called family left me

Hi i need help advice someone to listen. My 2 brothers beat me, my mother never cared for me. for her; the 2 sons only form her world . She never helps me rather worsenes my situations. Now i really realize that since childhood she humiliated me and i still keep on trying that she will love me also the way she loves her sons . But now i cannot try more i cannot bend further so as to break my back itself. My elder brother had a girlfriend and once while fighting as if usually does told me that his girlfriend left him because of me since then i was shattered now that sentence revolves in my mind and i keep on wondering is that the reason why he fights with me every now and then . My younger brother was was was my beloved one, but now he does not even talk to me . My mother too defends both of them when we fight and she also starts cursing me . In my so called family my mother and both brothers are excellent at back biting each other when my brothers are absent from room or home she will start telling me their ills but as soon as any of them will arrive she will behave as if they are the best and while fighting if i will repeat what she said on his face then mom will be far more excited to fight back SEEING ALL THIS I HAVE LOST ALL RESPECT FOR MOTHER and have lost all respect and love for brothers NOW THE TRAGIC PART IS AM LEFT WITH NO FAMILY AND I HAVE NO FRIENDS readers must be wondering about my dad -i love him and respect him but again for him i am just a girl whom he wants to get rid off easily making her marry am unable to study for last 6 months i do not get to in anywhere or to talk to anybody its not home but jail for me .whom to ask for help i do not know 3 people form group and fight with me beat me up worst part they form my family PLEASE HELP PLEASE

The problem is whom to ask for help and justice . I am not even independent in any way . I was never allowed to become so. I feel like to die but even in that case these morons will say to world that i was unsuccessful in studies rather than telling their own misdeeds
