You're A Vampire.
You are a vampire, my dear. Nothing else much to be said. I suppose you have questions. Yes, well... perhaps I can answer a few. After all, weren't we all Littlepires at one point or another? I think I'll pity you just this once.
We must make haste, though. I am a very busy man. Let us dine over a cup of wine and allow me the honor of telling you the tale. You're a vampire, and it's as simple as that, really.
