19 weeks and husband left for job

I was wondering if anyone has gone through what I’m currently going through. I’m 19+3 pregnant. Today my husband left for an oil rig job, till mid October!! They are gonna give him every other weekend off and let him have a week off for when the baby is born. But I’m so depressed today, everywhere I look I see my husband, I expect him to be around the corner and he isn’t there. It’s so hard, and I pry it gets easier. I know I wouldn’t be such a mess if my hormones weren’t so crazy, as it is. I’m hardly eating, like I try to eat but I get full after two bites. I’m just so upset, I have 3 kids not including my pregnancy. So I’m hiding my tears, but I know the sense I’m in pain. It’s just really hard, and I pray lord knows I’m praying so hard. For him to take over my pain. Cause I’m hurting. Just didn’t know if there are any woman who have been in my shoes.
