Downward spiral

I don't know why things have to be this way,my life is going under there is nothing left for me i need to end this i don't want to stay, i'm going down a downward spiral fallen further than ever before, i cant see any other way, it's as if i'm crying out but no one hears my shouts, where did things go so wrong seems i've lost my will to go on, i just feel everyone could care less i'm the only one to blame for all this mess, i don't see no light at the end of this tunnel i see someone digging a grave and it looks like i'm holding the shovel.
