First deployment

OMG, I never though this would be so hard! I feel such a void and miss my husband so much! I want to cry all the time and he just left yesterday. I hate that he will be gone for the remainder of my pregnancy and I fell like I'm missing my greatest support. I have friends and family but it's not the same. It's killing me that I don't know what he is doing and if he's okay. How do you survive 12 months of this???! Just needed to vent and get some advice.
