Thanks Trixi! Surprisingly, now that the day is actually here it's not as bad as I anticipated. I think just knowing it was coming up and that it would simply be no different than any other day was more depressing than when I woke up this morning and thought - okay it's Thursday and made my list of what I needed to get done work wise today.
I suppose eventually a year will come where I don't even think twice about what March 18th represented.
