Omfg!! I cant stand him!! Him an my mum split up when I was 7, an I can see why she split up with im hes a fuc*in a$$ hole im guna cut the story short as its really long..

     Hes an alchoholic, he has nothin 2 do with my older brother hes disowned him. My brother didnt do anything!! My dads nothin but a waste of space! Yer he works he has a new wife who hates me an I hate her! He never sees me, ever! My youngest bro who is 16 went 2 live wid him because hes going to college an its closer 2 my dad than my mums house, he get my lil bro everythin!! Crosser bikes, clothes everythin!! I get sh!t  my oldest bro gets nufink either. My dad never picks me up when I dont have money to get the bus 2 c him I've not seen him in over 6 months because he wont pick me up yet he takes my younger bro everywhere!! An he        p!sses me off I duno why I cant have a dad who loves me an wants me an actualy cares 4 me!! My mum has a fiance who she has been wiht for 11years an I love him 2 bits an hes even more of a dad than my real dad!! I get so p!ssed off an just wana tell my dad  what I think fof him but last time I did that he wouldnt spk 2 me for 9 months!! An wished me dead what do I do!?
