Does anyone else feel like they're still a child stuck in an adult body?

I'll be taking my licensure exam soon and after that I'll start to work, still I feel like I'm wearing someone else's skin. Peers who are the same age as me seem to have gotten their lives together whereas.... I'm still feeling stuck. I still have this kind of childish interests and hobbies, it feels kinda weird now but I still love doing it. It feels weird since it feels kind of shameful in comparison to others. I'm just looking someone who also feels the same way.
