Trauma.

I found you unconscious,
foaming at the mouth.
Failed to resuscitate you,
before my screams filled the house.
You were more than my sister,
you were my confidante, as well.
And since you crossed over,
my life has been Hell.
At least we were together,
holding hands,
for a quarter of a century.
All I can do now is accept that
you are no longer here with me.
