The person you were in the closet was a skin you needed to shed in order to grow, but that knowledge doesn't stop you from grieving them, missing them, and who you were when they were you. Try not to punish yourself for that fondness. You are allowed to love the people you have been, just as you are allowed to love the person you are.
"Hey, are you okay?"
"Just feeling some closet grief today, thanks for asking. I'll be okay once I listen to some Robyn."
