The importance of diastole

I need a β-blocker or something like it.

My heart is …
Empty, Drained, Void, Siphoned,
Exhausted, and Depleted

Because at times my empathy …
Trickles, Oozes, Gushes, Seeps, Dribbles,
and Pours out every day.

Who has time to …
Reflect, Refill, Recharge, Replenish,
Restore, or Revitalize?

Why is my diastole so short?
My heart needs more rest time.

I need a β-blocker or something like it.
