If it doesn't come back, then maybe it leaves room for other feelings to develop and grow? I'm talking lifelong, rather than over the course of six months or a few years here.
Patience? Compassion for your own suffering and the suffering of others? More focus on self development? A greater sense of self? A better understanding of boundaries? A greater appreciation of the small things in life? The capacity to find joy in little moments in time? A deepening sense of peace and calm?
