I went too far

Yesterday I went too far with my exercise and restricted too much. Consequently, I've had heart palpatations all day and managed to wear the skin off my tailbone. I guess I'd forgotten that can happen even at a fit and healthy (haha) weight. Plus my vertebrae are bruise and swollen to the size of prunes. NO MORE SIT-UPS!!!! (Unless I do them on my padded exercise mat.) I also tweaked my right hip which has bothered me off and on for ten years-- thanks to all those leaps and jumps. Sure, I had fun doing it, but I am not Nastia Liukin, I don't have the conditioning to perform these moves, I cannot be doing these things with weak joints and brittle bones! When will I learn, when I'm wheelchair bound? Why am I always pushing the envelope when it comes to my body? I wish I could learn to push where it counts, like in school, at work, in relationships (oh wait, what relationships??) I used to be a high achiever in music, art, and school. I play my instrument or pick up a paintbrush once every few months now. I used to spend 20 hours a week (at the very least) with my art and music. Now all the energy is siphoned into something that doesn't matter and actually harms me. Even though so many positive things have happened in recovery, the exercise is still a problem, though a lesser one. The good news is, I have a LOT of energy, if I could only redirect it.
Hey, I should volunteer for Habitat for Humanity! That way, my energy could be channeled into something worthwhile :)
Good idea. . .
