First time mom to be

I'm currently 22 weeks with my first child a baby boy. Hubby and I couldn't be more thrilled!!

I'm due Jan 21st. I have to say this I'm absolutely terrified of giving birth for the first time!!! I have nothing to compare it to and everytime I think about it I freak out and wanna start crying! I'm overall pretty tough but I can't stop thinking about what's going to happen. On top of that my husband is set to deploy for a year after I have our son!! I'm just wondering if any moms out there had the same feeling and what did you do to get thru it?

It's almost 3 am my time and I can't sleep knowing it's getting closer to my due date. Oct will be here soon enough. Any thoughts or helpfulness would be greatly appreciated. Thank you so much!
