Hi Fly:
I think that you are ready. Have an exit plan. Keep SR open in your phone and step aside for a second and read or take a peek when you go to the bathroom. Think about it. You are going to be present, not feel crappy, remember everything, do everyone a favor by being DD. This is the you that YOU want to be and others will admire you. What a great example for the children in your family. Almost a year is amazing.
