Roleplaying Anyone?

So lately I've been getting into roleplaying a lot- or at least the thought of it. So far I've just been busy building character concepts though I did decide to convert one story idea to the purpose. I'm supposed to be writing up a post. The problem is, my writers block has seen fit to return with a vengeance- just when I was starting to get going again. It feels like I can still write. I just have to bang my head repeatedly into the cement wall before me first. Then, when I'm all bloody and have a slight concussion, I'm able to move past it and type up some sort of garble. It evens feels that way right now- like I don't know what to say. What do you guys do to overcome writers block?
