First person present?

I started work on my first novel this past week, and I ran into an issue with trying to decide on the point of view it should be in. I guess to make this a little more clear, it has to do with the nature of the book, and why I ended up choosing first person present.

I am writing about a guy, who at the core of his being, is delusional, has hallucinations and a bit of OCD thrown in. It is his firm belief that under the direction and insistence of a group of people who are changing the world for the better, he must burn homes and business that have to pay for the choices they have made. There is no religious connotation to this (and I don't plan on introducing it at any point, but you never know I guess).

For this type of character, I just felt that third person would be inadequate. Yes, third person would have made a possible parallel story of law enforcement chasing him a bit easier and fill some pages, but it just didn't feel right.

I have therefore come to the conclusion that the book needs to be in first person present. What does this mean for me? It means I have to scrap what I've written so far and start again. I was using "I" once every 15 words and it sounded horrible. I do however feel fortunate that it is early enough in the process that I can fix it, and make it exponentially more readable.
