Is anyone else panicking...

About returning to work after maternity leave? I know I am going to cry so much and have serious separation anxiety. Not only that, but I am already starting to feel guilty for needing to leave him at a home daycare all day every M-F...and missing his milestones and feeling like he would be feeling abandoned or neglected by his mommy. I know it's part of life, but I just can't help but feel anxious, overwhelmed and sad.
