Princess Twilight Sparkle, or so she's titled as, simply hasn't felt much like one. She's respected as a princess, greeted politely as a princess, but unlike Celestia, Luna, or Cadance, hasn't had any duties of one.
Caught in-between her expectations of the life she'd lead and the life she's actually leading, who could blame her when she feels like a zombie? Speaking of which...

So many errors...
Before reading: so, someone else noticed that the Elements vaporized Twilight, meaning she's undead now (and also possibly Pony Jesus)?
Now: no? Oh well. That's good too.
this does indeed have an ending
