abyss, n. There are times when I doubt everything. When I regret everything you've taken from me, everything I've given you, and the waste of all the time I've spent on us.

Framed as a dictionary entry (“abyss, n.”), the line treats emotional collapse as something definable: an “abyss” is not only depth but a state of mind where certainty, gratitude, and even the narrative of a relationship fall away. The speaker inventories loss on both sides—what was taken, what was willingly given, and the irrecoverable cost of time—suggesting that the deepest despair comes from realizing one’s agency in the damage. The repetition of “everything” intensifies the sense of totalizing doubt, while “us” implies that the relationship has become an identity the speaker now questions. The quote captures the moment when love is reinterpreted as depletion rather than meaning.
