I wouldn’t be against it. After all it’s the story of my experiences. From my point of view. So, I mean that would literally make me the main character. No “syndrome” necessary.

I would also like to point out that in many stories I am far from the main character. I am simply someone that was present for something unusual. For instance, One time I accidentally hung out with a murderer a few days after he killed, but a few days before he turned himself in. He only told me this once we were alone, and he went into great detail. I'm not the main character in that one. It's just told from my perspective.
