New mom, back to work sadness

It’s 11 pm and I’m just getting in bed free prepping for my first day back as a teacher. I was lucky that I was able to take a long maternity leave, but tomorrow it’s all over. I feel a lot of things- guilt, sadness, nerves... i know most of you have probably gone through this. How do I tell myself that it will be ok to put him in someone else’s arms? When he’s sad and wants me, I won’t be there to hold him. He is sound asleep and has no idea that, beginning tomorrow, he will see the babysitter’s face more often than my own.
