pregnancy question

Well, I would like to give you guys a little info about me! Im a 20 year old African American who is about to be a first time mom. I'm also a military wife/brat so as of now I'm currently a stay at home wife! As I sit home alone sometimes I get so nervous about becoming a mom. I literally know nothing about babies! lol. I'm so confused as to what I'm going to do with a new born baby. My family lives in GA & I live in WA so we are very far away from eachother. Any tips as to what I can do to prepare for when baby gets here?
