To GF - Well, that's the thing. I write random nonsense every day, because if I don't keep writing, or if I'm not creative like that - I start to feel odd. Like my sig.
I write little tit-bits of everything - scripts, situations, I make up characters, I write random dialogs between fantasy people - everyday I do that. You've hit the nail on the head, it's just that I've been doing this for so long. I'm not 'stuck' in the writer's block kind of way though. It's just that everything's very complicated at the moment and it's hard to get anywhere.
It's basically a case of trying to complete a whole new idea, and then try and fit it in with what I've already created over the last 2 years. And it all has to make some kind of sense and link in together. It's pretty much impossible, at least at the moment.
