I tweeted tonight that I was "Allowing myself to descend into a slough of despond as I know I will emerge all the quicker if I don't fight it."
This comes about every month or so and is a result of trying to be good for too long. Trying to be successful, trying to be healthy, trying to learn as much as I can, and trying to be liked by everyone. After a few weeks of this my bad fairy has had enough and starts saying "fuck it".
Way back I used to handle this by going out on my fast motorbike and scaring myself and a few car drivers. Then for too many years I handled it by drinking myself to a standstill (which was a not inconsiderable feat).
Nowadays, having given up biking and drinking, all that is left to me is to eat crap and surf the web too much. Thankfully I am much more aware of the process and by not fighting it come out the other end quicker!
