How am I going to go back to work after my leave?

I still have 7 weeks left with baby before having to return to work. I’m already getting emotional and anxious at the thought of having to be away from my baby boy five days a week😩.. I feel guilty honestly knowing I’m going to miss out on the majority of his life.. I mean seriously how do you working moms do it?! If I could stay home I totally would and daycare is so expensive I’ve thought about it but my job is too good to give up and I will eventually have to start working again someday.
