Ugh, it's been 3 months since I could write more than 3 sentences and nearly a year since I've finished a story. I desperately want to write, something, anything. Something that'll fill this void of not writing. Words and phrases flit around in my head, characters that are fleshed out in varying degrees poke in every now and then, I just don't have the vessel, the story to let them out. Only bits and fragments. The young mage got exiled to a foreign land where his magic doesn't work. What happens to him? The cynical once-human ghost-catching office employee got her deviant teenage angsty spirit. What else does she do? A whole fantasy world about 70% built is there. How do the main characters live in it? It's terrifying, the notion that I might never have a new story in me.
Oh the fellow feeling here.... have you tried clustering?

It sometimes works for me, as does simply sitting and writing the first rubbish that comes into my head just to get going (it very carefully gets deleted later of course )
I love those character ideas! Do you 'cast' your characters? I find that sometimes helps because I then hear the voices....
