26wks and scared out of my mind!!!!

I was totally fine up till last week, now I'm like "Oh I'm having a baby and need to come back to work by February"...this has started an array of emotions for me and it doesn't help my husband schedule has been changed and we don't see each other ever. I try to relax and calm down with some breathing but then BAM the thoughts start😱 I don't know what more to do!!
