Anxiety about tommorow

OMG! I am freaking out about tomorrow! It is the first BIG step towards our foster license. A friend is a few steps ahead of me in her process and said not to worry, it will be fine. But my brain is on over drive thinking of all the bad things that could happen.  My house is in ship shape condition-yeah! I bought food for tomorrow-muffins and fruit (9am appt). I just need to chill and take deep breaths and RELAX! Oh my goodness, I am so nervous and excited at the same time.
