Nanowrimo Blues

It's the final week and I only have around 17,000 words with no sleep and petrol driven arms I might just get to 50,000. I think that the problem is that I worry I won't write enough on each bit but then when I start a chapter it seems to flow. But then that's maybe just an excuse and perhaps I should be working on that rather than waffling on her about my Nanowrimo blues.
