I'm looking at the Mama in the mirror...and wondering WTF?

I must be coming down with something. What else could explain my behavior today? Why the worry? Read on, my friends.

• I walked the kids to the bus stop today and got there early.
  
• I showered before 10am.
  
• I wore make-up.
  
• I dressed respectably. I actually looked like a honest-to-goodness PTA mom rather than a yoga-pant-wearing poser.
• I walked into Target and walked out -- empty-handed. (I know, GASP!)
• I skipped the gym. I went to Taco Bell.
• I worked all day on the computer without visiting www.athleta.com and buying one more skort.
  
• I wore an apron to cook dinner.
• I baked and frosted 72 cupcakes. Yes. 72 f-u-c-k-i-n-g cupcakes. If Madan ever accuses me of not loving him, I will frost his head and turn him into #73.
• Did I mention that I wore an apron? Yes, an apron -- with my PTA-mom clothing underneath.
  

My identity crisis didn't hit until shortly after the last cupcake. I'll refer to him as "72" for short. After icing "72," I paused. I reflected. I got dizzy. (The sickeningly sweet smell of cake batter had taken the house hostage.) Then, I got angry. I looked to the ceiling. I held up my chocolate iced hands (which were coated with darling little sprinkles) and screamed, "WHO AM I?!?!?! WHAT HAVE I BECOME?!??!! THE WOMAN I KNEW WOULD HAVE DONE STORE-BOUGHT TREATS! THE WOMAN I KNEW COULDN'T BAKE A CUPCAKE EVEN IF HER LIFE DEPENDED ON IT!!!! WHAT HAPPENED TO THE GIRL WHO BROUGHT A BAG OF OREOS TO THE SCHOOL PICNIC INSTEAD OF A HOMEMADE DESSERT? WHY THE HELL AM I YELLING AT THE CEILING?"

I'm looking at the Mama in the mirror and wondering if she needs to change her ways? I don't know who this new chick is, but she's wigging me out.
