By the way, if you're interested, there's a community over on Dreamwidth that is doing a WIP challenge. I participated for November, and it's made a huge difference. They're doing it again in December. You say what challenge you want to take on -- a certain number of words written, a chapter finished, a fic finished, whatever -- and then get assigned to a "buddy group." You can then ask your buddies for whatever support and encouragement will help you meet your challenge. There are also weekly check-in posts for the whole community. Despite the "challenge" aspect of it, it's very casual and informal -- all about helping writers, and not about causing additional stress. It's about you deciding to set a goal, and the community trying to help you meet it.

If you want to take a look, the sign-up for the December challenge is here: http://writethisfanfic.dreamwidth.org/7114.html
