Hi Alyssa. A good heart comes from within us not from outside of us. How we feel about others tells us as much about ourselves as it does about those others. "A flower that blossoms only for a single night does not seem to us on that account less lovely." (- Freud -). Change and transcience are inevitable and, as such, we embrace it and grow from it.. Regret is a fruitless state to hold onto.
