If ever there was a legendary figure who was CrossFit...Pai Mei is it!
You crashed and burned buddy! I did that too when I started. The link Beth posted is the "secret to success" that no one reads. I read it properly, 4 months after starting and crashing...then I started again at low low volume. It's took me from June 04 - Jan 05 to be doing this as prescribed. Don't worry about not getting as great a stimulus as everyone, at the pace you can move from a diluted WOD you would be getting a far better workout than plugging away for ages at the prescribed workouts.
It's my experience and I'm certain that of many others that this approach will develop the greatest fitness gains and adaptions.
