Sore knees, broken cleat, exercise bulimia

I woke up happy to work out, but some stuff hurts. Like my knees. And then in indoor cycling, one of my cleats broke, so I couldn't do any standing climbs and I had to be really careful about not flying out of the pedal. Then I wanted to run, but I couldn't - so I did 20 minutes of brisk walking, and I think tomorrow I will be able to run again.

Okay, on exercise bulimia: I read an article yesterday that said that bulimia can include people who don't actually throw up. Instead, they:

-- Exercise excessively
-- Punish themselves for overeating by exercising more
-- "Earn" foods by exercising

I totally do all of these things. Am I bad? Am I unhealthy?

I wish I didn't like food. It would make things so much easier.
