Why shouldn't I be well, when your arrows of cruelty are countless, and your strikes are manifold?

This powerful couplet speaks of profound resilience. The speaker challenges the beloved, asking why they treat him as if he is fragile or easily broken. The underlying message is that the speaker has endured so much pain—so many 'arrows' and 'blows'—from the beloved's cruelty that his spirit has been hardened. It's a declaration of survival, a refusal to be victimized again.
