Irregular

My heart's irregular beat
within my chest.
A physical event or feat
causes me to rest.
The soul I know, lies within,
undisturbed momentarily.
It's anguish will soon begin
when observing the futility
of fighting a disease this grim,
that borders on absurdity.
But fight we must, I say
It must readily need to be
for our life this way
is not certain; this we see.
