I want to stab myself in the head till I can't think about anything anymore

"I don't know anything anymore, My life is utter shit... I lack anyone who cares about me..... My brothr just leaves me alone... I fought so hard to live with him and spend time with him and he just leaves me be... he brought me to london only to leave me in the house by myself =/
I feel null inside
I have nothing else to live for... I can't sleep because I'm scared of dreaming and when I dream I dream about them and when I wake up without them it is hell. I have lost all will to get through each day
I just want to lay on the floor and never move and have my sister come lie with me but she won't ever
I miss my Poppy and I want to go back to live with him but I don't know... I want to sort things out with my brother first but he won't talk to me
I'm invisible to all my fucking friends and np-one at this point cares if I live or die... and I'd much ratherdie then spend anymore fucking time in this place and I've tried soo many times but I can't never do it
I can cut but that only takes the pain away for awhile... I've tried Oding before but I can't even fucking do that right
I need my head to be ok but it just won't be
I need someone to love me but I can't find anymore./.
to sum up
I want to stab myself in the head till I can't think about anything anymore"
