Lost my entire personality after becoming a dad. Help?

I used to play in a band, went to concerts every month, travelled, read actual books. Now I'm just dad guy. All conversations are about sleep schedules and daycare costs. My buddies still hit me up but I'm always too tired or broke or have some kid obligation. I love my daughters but I feel like I've disappeared somehow. How do you guys balance staying yourself while being all in as a parent? Am I just being selfish?
