In need of some encouragement..

So I found out I was pregnant yesterday morning. Yay!! So excited. Can't wait! Hooray! Been wanting this for months!!

Husband is in the military. Husband had a 1% chance of deploying. Guess what we found out today? Husband deploys in July. He'll only be gone 6 months. He'll be back in January. That doesnt seem too long. However I'm due in December. Which means he'll miss the whole pregnancy. All the exciting parts. The first kick. The contractions. The birth. The newborn phase. Everything. He's gonna miss it all. I dont know what to do. I haven't stopped crying since he told me. I dont know how I'm gonna make it through this. I have a son from a past relationship and he's only 10 months old. I'm gonna have 2 under 2 and he won't be there. How am I gonna do this on my own? My parents live in Texas and I live in illinois so they arent much of an option. We just signed a year lease for a house with a friend and so I cant move down there either. I'm a mess right now.

Help me. How do I get through this without having a mental breakdown? How am I supposed to do this?
