This is true to some extent - use it or lose it. They also teach you to know your limits so your pain doesn't flareup and put you in bed for a week. You learn this delicate balance this over time, to push yourself just enough but not too much. At first you hurt yourself constantly because your body can do whatever you want - right? But no. Not now. That fact doesn't really make it easier to get out of bed. Your brain tells you not to move, that you're injured. Rest. Its an animal thing. You have to overcome it each morning, and all day long. And unfortunately that takes energy. It drains you. You have much less capacity as a result. Everything in life is harder. You do the best you can. This is the reality of disability. It fucking sucks.
