Scared to be a mom? 😳

What advice can you give me if I'm honestly scared to be a mom? I mean I LOVE my baby already, but I feel like I won't know how to do anything at all. I haven't even changed a diaper ever in my life. I also have never been super good with little kids, I'm hoping since this will be my own baby I'll feel differently. Please give me some wise words because I want to be the best mom I can be.
