Want to kill myself

I just want to kill myself. But i dont have the courage anymore...
I dont know why I live anymore. my life sucks...
getting up....eating a bun at about 11 in the morning and sleeping until about 4 and eating bread or cornflakes...and going to bed ...
I might as well just die in the room....no one is going to even notice ..until ofcourse my body starts smelling...
Have had enough of crying and sleeping ..
why did this happen to me ...
why did she do this to me ...
