Returning to work

So I returned to work back in February after having my baby, but I was out of work for the past 2 months due to medical reasons. I have to return to work once again tomorrow and I'm breaking down inside. I took the baby out of daycare while I was home and I loved every min of the bonding. I'm going crazy knowing that in a few short hours I will once again have to be away from my baby for 10 hrs, once again have to pump at work, and once again put my baby in daycare...I've been having mini panic attacks anytime she's away from me for more than 15 mins the entire weekend. I don't want to leave her again...she's so much happier when I'm home with her. Idk how I will do this tomorrow...
