Emotional Wreck

My husband left for the police academy today. He'll be gone for a week. I'm 6 wks 3 days pregnant. My emeotions are all over the place and the second i got home from work I started bawling. I just miss him so much already and I have 6 days left to go. Anybody have any advice as to how I can keep from crying everytime I think about him? It's not good for me to keep crying constantly because it stresses me out and that's not good for baby. I struggle with anxiety too. Sometimes it's bad. I've never taken medication for it because I don't feel i need it. I'm just sad because it's the first time in 3 1/2 years we've been away from each other for this long. Someone, anyone talk to me!!
