Pregnant while my husband deploys

We just found out I'm pregnant and I am so happy! We have a son already and he just turned two. I've been wanting another for a while now. We finally get the news! YAY!!I THEN it all sinks in. My husband is deploying and April for 400 days. Baby is due September. My husband won't meet our little one until they are 9 months old. It breaks my heart. I'm going to have to do this all alone. My pregnancy, raising two on my own, my labor, my recovery, everything. It scares my to death. My baby won't know their daddy when they first meet. I don't know how to deal with this. I'm also a full time student and I work at a school as a para. I don't know how anything will work out and it scared me to be in the dark. Has anyone gone through this? PLEASE HELP! I could really use a friend and support.
