Need help with a book I'm writing...

[HydraMoon]

I would skip schizophrenia and stick to a broader 'psychosis'. Research and read read read about mental illness. Skip movies and fictional work about mental illness- go for nonfiction journals/personal accounts of what it's like. Media tends to get it all kinds of wrong.

You will still have an issue of an unreliable narrator but that can be gotten around. Perhaps the real narrator is the convention itself. Does this man need to be the focus or could the convention be the center instead? Like he's being 'born' and the convention is the mother. Could easily parallel a past relationship he's had with his own mother.

I'd suggest reading a memoir of a person who has Shizophrenia. It would probably help you build your character to be someone who actually has feelings that people with the illness can relate to, as well as behaviors.

I'm not sure what ideas I can add to it, as the story doesn't really appeal to me.

Answer everything as you go along, give a reason to each action--may it be because of his personality, or because of something else.

One thing that helps me is to pretend I am the character and everything I'm writing about is what I'm actually seeing and doing.

I'm not sure if those will help at all, but I say them all the same.

Good luck with your book. (If you find it difficult to make into a whole novel, stop and see how you can begin to start making the ending clearly in sight. Then, reach for that.)

One thing I'd say... You have a lot of "Maybe"s "Probably"s and "I guess"s regarding your character's psychological profile.
As a quick tip - Get it right, be realistic, and don't run away with a poor imitation of glamorized mental conditions for teh lulz. Particularly if you go the Schizophrenia route. People always seem to get that wrong.

But it sounds interesting. I like the "I don't know what's worse, if I'm hallucinating or if that shit was real!" aspect of it.
