Returning to work...

FTM...help!!!! I went back to work today and it sucked. I was so emotional and distracted all day. When i put him to bed last night i just cried. I miss him so much and it makes me sad to think someone else will be raising my little boy and i may miss important milestones. Staying at home is not a financial option for my family. Please tell me it gets better. What are some things other moms do to make it through the day. Picture for attention.
