Measure of Pain

Could you measure the pain
I am going through
Could you measure?
Measure it any how?

In Miles, the distance
I ran,
to run away from miseries.
In Gallons, the tears
I shed,
in many nights in many years.
In Tons, the load
I carried,
on my chest through
this long journey.

Its pain all over
in miles
in gallons
in tons.

Could you measure?
