I've been writing (and re-writing) something for a good number of years. In the development of the story, it kind of felt like I was finding myself. In this, I feel that the fantasy world I've created is having an effect on me philosophically. While this might be a good and a bad thing, it also dangerously blurs the line in my head and in my heart between reality and fantasy. I know this isn't a philosophy room, but I think this has happened to other authors too.
My question is:
Is this something that can be reversed, or am I better off leaving things as they are for the purpose of more writing in the same genre?
