The end of the rope

I've been thinking lately about just leaving. Taking my car and driving it as far as it will go and once it runs down, going to the closest airport, buying a ticket and hopping on the next plane to somewhere. I'm sick of not having a worthwhile job, no close friends, or family. It seems my whole life has been on the shit end of the stick... no mom, no dad, no encouragement, no family, my closest friends gone, always being last on the list, and no will to continue. Sure I have a boyfriend and a cat but is that truly enough to hold me to this place. Wouldn't they be better off without me? Even I would be better off without me. Now if I'm coming to the end of my rope I have to determine if I can just let it go and keep on climbing or is there a noose instead of air.
