Analysis of My two sons

My two sons

A little while ago they were right here,
They'd say, don't fret, you worry so, mother,
I could feel them, hear them, touch,
We lived life, didn't think too much,
They were my sons, good kids, teens,
Normal, ornery, taunting, full of beans,
Trey, my eldest was tall, we called him shorty,
Dexter, the second, smaller but more sporty,
I just want to tell everyone,
How they bathed on the beach in the sun,
They dutifully went to school,
Pushed and shoved, played the fool,
Trustingly obeyed the compulsory mandates,
Girls, they played the field went on dates,
I know its futile, but I wonder where they are,
I feel them nearby watching me bake or so so far,
They surfed for hours in the sea,
Raced down the beach fast and free,
They would run around in the rain,
They didn't care about the lightning and thunder,
They were so full of life nothing could get them under,
Sometimes they would be annoyed,
I didn't care. Now I'm in this void,
Myocarditis, from what does that stem?
How could something like that take both of them?
