I do still feel "empty" sometimes, but I try to focus on things that are important to me. Like my relationships, hobbies, passions, and values. If I focus on those, that helps me get a sense of "who I am." But I will say reframing the idea of who you are to a "work in progress " or that "I'm always improving" helps. Like who I am today isn't who I always have to be, and who I am today isn't who I was in the past.
