Does anyone ever feel completely lost in their own identity?

I'm not complaining about being a dad because I love my kids more than anything but sometimes I catch myself and realize I can't remember the last time I did something just for me. Used to play in a band, did gigs every other weekend, had this whole thing going. Now I'm the dad who knows every word to Bluey and can change a diaper in the dark. I looked in the mirror yesterday and didn't recognize myself for a second. Like not physically but just... who am I outside of being dad/husband/employee? Did anyone else go through this and figure it out? How do you find yourself again while still being fully present for your kids?
