This has happened to me also, a feeling of losing yourself and wondering where the passion went. But I believe its the body's way of taking a forced break and recharging. I decided not to watch my averages as much and just wanted to have fun on the bike, ride more with people instead of against them. I ride far more offroad then on, but the feelings of burnout are the same. You have to put the fun back into it and take the pressure off. That's why I don't want to compete, I love cycling and want it to be this activity that relieves stress instead of creating it. Good luck and hope you feel much better soon. P.S. It doesn't help to 'feel' out of shape either, once you shed a few pounds and see the muscles outlining your legs again, it'll help too!
