Scared to death.

Well tomorrow is my first day back to work since my loss. I am so scarred how I am going to do. I had to hold back tears today at the play place with my son when out of the other 2 moms there one had a 5 week old and one was pregnant and booth had children the same age as my son. What am I going to do in the middle of a delivery?? Just start bawling?!?! Well see how this goes:-(
