Sick of feeling depressed and no one caring?

ok so im 13, my dad used to sexually abuse me, force me to suck his penis, have sex with him while he did what he want to me. i was 8, my uncle watched. my mum knew about it but didnt do anything. it stopped after 2 years because i came out with it and told my nana, she took me to the police but my 'dad' didnt get sent down.. then she took me to a councellor and i got diagnosed with bipolar clinical depression anger problems and social phobia.. you'll see why. my whole life, i got neglected, never got fed. for 5years i only ate pot noodles because the house was a mess and we coudnt access the kitchen to eat. i seen my brother almost masturbate, my brother have sex with my sisters bestfriend, my mums rude texts and pictures... i told my sister and she laughed while i poured my heart out. my brothers and mum beat me up because of the size of my breasts, she choses drugs sex and alcohol over me.. havent eaten for 2days because shes been out with this guy.. tried killing myself 13 times.. i just feel like im at a dead end because no one can help me get out of this, if i try to express my feelings such as crying or getting angry, i get shouted at or beaten up and i get told to get over it. im not allowed to be me.. i just want to die. sick of people lying to me. treating me like crap. hurting me like i havent got feelings. talking behind my back, calling me names like you sl*g, prostitute, ugly b*tch, sl*t. got told i was a mistake. and i think i am, because no one loves me now my nana's dead.NO ONE.
