Writing help, please! :)

I've got this really hideous writer's block thing going on, it's truly ugly. Totally deadstop in the water kinda block. At the same time, I'm really desperately wanting to work on Public Enemies. Probably no one remembers that fic, it's been so long! The thing is, the new ideas go off in a different direction, which means a totally different ending to the fic than what I first imagined a few years ago. I'm not sure if I should rewrite the fic--the parts that are still just a loose collection of notes--or try to stay to the original outline. The way I want to go changes it somewhat but not the total flavor, plus I think it will shorten the story. Dean will probably end up being slightly more a victim but also maybe a harder character.

What do you all think? Would you chuck an outline, or try and make the fresh ideas fit with your original vision? And does it matter if the fic is more than a year old? *hides face*

Help me get this fic on the road again, beloved flist!
