Does Writing Fiction Change the Journal Relationship?

I am so solidly writing my fiction at the moment, that the main characters are following me wherever I go and every thought I have. Now please don't go and get the men in white coats and have me put away. I suspect it is a common phenomenon for all writers of fiction - that the characters develop to the point of being a real part of your life. Without that feeling I couldn't write.

"But what I have noticed is that my writing in my journal and blogs has decreased significantly during this fiction writing obsession."

So ... what does that tell me about journal writing in my life? I think the question it raises is "what is the relationship between writing as work (fiction or not) and journal writing. Like I can imagine a life where I write possibly every waking hour that I am not involved in self-care. BUt somehow in a life where I also have to juggle emotional and practical tasks and relationships, my writing time is ver precious. So am I in fact choosing one or the other? I hope not ...

What makes me write less if not the fact that I am writing more in another area of my life ...
