long-distance only child of a divorced father

Is there a word for
the way that my worry
wells up in the middle of my chest
and condenses itself
into a magic 8 ball

I want to shake him sometimes
when we talk on the phone
and I hear his hacking cough
I wonder if he's really

cutting back on smoking
outlook not good
walking to the rock river
cannot predict now
wearing a mask in the grocery store
my sources say no
