Also It's easy that you begin abusing exercise. To compensate for eating, or to get rid of anxiety or that you end up doing more and more exercise just pushing yourself harder and harder. And that Is not good.
Even if you love exercise, don't let it be your only motivation to recover. Because then its easy to over exercise as it was your only reason to recover.
Remember that exercise should make your life better... be part of your life. Not the only thing in your life.
I know its tough for many to be restricted with exercise but its for the best, and its only for a period of time. Its better that you focus on other things like resting, eating, maybe meeting friends, baking/writing/watching films/playing music etc etc
