Going back to work tomorrow:,(

After being off for 3 months I have to go back tomorrow and I begin working full time again. Im so upset. I don't want to miss any milestones with my daughter or for her to not see me as much. (Ill be working 40 hours.) The only positives is that 1. MONEY..and boy so we need it 2. Im 5 mins away from my house 3. My daughter will be with my mom when my husband and I are at work. I know its a good situation compared to some moms have but im sad..any other mommies?
