I was the talk of the town. A little, bubbly mare with a pink coat, mane, tail, and a cheerful attitude in any situation. I would plan parties; it was my special talent anyway! Ponies loved me, and I loved them back.
Sometimes a pony would come to me. They would usually put on an embarrassed smile and ask: “Pinkie Pie, can I have a party for *Insert somepony here*?” Of course, I would always reply with a giant grin and squeal “Yes!” Everypony deserved a party!
Thoughts fill my head. Like every other pony, they are usually about plans. When does this happen? When should this happen? But mine were different of course. They would usually consist of: What frosting? When did I plan this party? Is today Fluttershy’s birthday?! Normal thoughts for me.
But sometimes, they would turn dark.
I would be walking along the streets of Ponyville, or baking, or talking, when I would hear something. Usually something whispering in my ear. Then I would feel it. My mane as it would convert from its bouncy style to flat and straight as it fell onto my withers. The sensation as my vision would turn darker, along with my blue eyes. My thoughts would change.
But it was all in my head. 
My vision did turn darker, but my mane and eyes kept their color and style. I didn't know, but if anypony noticed, they would only see my expression change. Nothing about me would change physically. 
But, every happy thought would crumble into deep darkness.
I hated it. Absolutely hated it! It has been ruining my day-to-day life for 5 years. It would usually come when I was talking about my friends. As soon as I felt my demeanor change, I would have to make an excuse and get to Sugarcube corner, fast. Only one pony other than me knew.
Sometimes, somepony would catch me on my sprint back and would ask questions like:
“Are you all right?”
“Are you ok?”
And the worst of all was: “What's wrong?”
It was terrible, the worst question I have ever received.
Because I can never answer truthfully.
Because……
I really don't know.
