anxiety of going back to work.

Jessica • Im 26 and this will be my second pregnacy

I really don't know how to handle going back to work I really have problem with being away from my little man. little back round I had a angle 6 years ago and went back to work 6 week's after he was born my mom normally watched him one weekend she was out of town so the baby's father watched him it was not the first time he'd watched him alone but normally he only watched him 3 hrs maybe 4. I had an 8hr shift. I only 3hrs in to my shift when I got a text that would change my life something was wrong with my sweet angle and after test at the hospital he was declared brain dead worst days of my life and now that I have a new baby and I'm suppose to go back to work in a few days I'm freaking out. I have a great guy now and he's wonderful with our son (but with my first sons father I never had and indications that something would happen) always changing, feeding, talking to home calming him ext. I don't know how to not be so scared even though I trust my fiance I'm still nervous.
