How can I be a mom when....

I still need my mom! Ugh feeling scared to be a mommy!!! It's not like I rely on my mom, or she supports me financially etc... I'm 30 years old and happily married. But my parents and I are very close and I still turn to them for support etc.... Does anyone else feel like they are not ready because You feel like I will always be the "child"!? I don't know that sounds crazy.... What If my maternal instincts never kicks in etc...
