Still haven't figured it out.....

The walls are closing in around me, there's no way I'll let them get me now,
But it's hard to hold them up, When everyone around me let me down.
So I try to pick up the pieces, With a world of burden on my back,
But a rattled brain and chest pains, Indicate to brace for heart attack.
Is the danger an internal one?...Will that final fleeting breath,
Be a death from natural causes? Or a natural cause of death.
Is this life I chose the lonely road, Paved with rage to warm the cold?
Or is there one with hands to mold this desperate man, whos' soul I sold?
Is this life a life worth living? When my only sight is seen in red?
Is it better to sleep alone at night, or have a corpse inside my bed?
"Who knows", I tell myself, As I struggle toward the edge......
You never know how hard you'll hit the ground, Until you leave the ledge.
