I think this song is about someone holding a grudge against someone else for a long, long time, and she finally forgives them and how that feels. "what I taste is bittersweet" could mean that it is bitersweet to let something go, because it is, in my opinion. It's freeing but also constricting. You have to really forgive them and that's hard(bitter), but you can be friends again. And that is very sweet.
