The big 3-0!

Ahhh,

I am now officially 30. It is depressing to even think about but I am the youngest mom at my daughter's elementary school and I have accomplished a lot. So, why this feeling of sadness about being 30? Could it be that I am so much closer to 40, or that much closer to death, or because the 20's are behind me? I can't go back, just forward, so I should make the best of it. :-)
