Sad and in my third trimester

So my husband just deployed yesterday. We have two kids one 8 and other just turned 2, and of course I’m almost 29weeks pregnant. I keep having meltdowns and just crying so hard. My daughter has no idea where her dadda is and that makes it so much more worse for me. She was at the bottom of the stairs last night thinking dadda was upstairs she was at the bottom of the gate calling his name and I told her daddy is at work and won’t be home for a long time. She just broke down and started crying saying dadda she has an incredible bond with her dad. And my son understands but cries for him as well. We are a very close loving family I mean all our time is spent with each other. Both kids slept with momma last night, they needed it but I needed it as well. First night down just 276 more sleeps left. It’s so hard and it’s not the first time but my daughter was 3 months the last time and didn’t know now she knows her dad. And my son hates it idk if it’s because I’m in my 3rd trimester and my hormones are all in a rush so I cry about everything I really hope this eases up. 😢😢😢🥺🥺
