Going back to work

So I’m going back to work in a week and a half. I’ve literally been crying every day. I’m going to miss her and she needs her mama. My mom is watching her for us so I know she will be in great hands but I just don’t know how to pull myself together. I only work 3 days a week but they are 12.5 hour shifts so I literally will only see her like 2 hours a day. Ugh I just keep telling myself I will have 4 straight days with my little chunk after. Any suggestions that made it easier?
