Who Am I? (TF2 Pyro Fanfic)

I got bored... so I wrote a draft of a Pyro fanfic I made up.
If you're new to TF2, then you probably won't understand this, so I'll explain. In TF2, the Pyro is a mumbling, mentally unstable pyromaniac whom cannot speak due to wearing a gas mask. The Pyro sees through a twisted world called Pyrovision, in which everything is pink and full of rainbows, while in real life he is brutally massacring the other team.
