Struggling with Chronic Pain as a Ballerina

I'm having lots of pain tonight. It's definitely my fault and could he avoidable, but I don't want to give up doing what I love. I dance in a ballet company and help run the company at my college. This week is our show (we are doing the ballet Coppelia), so I've been very busy in long rehearsals every day for over a week. I keep coming back to my dorm at the end of the day full of bruises and pain and soreness. which to some extent is normal, but I can't help but wonder if other people are really just getting to go home pain free (or at least with significantly less pain). It's so frustrating living in a body with chronic pain. It's so frustrating wanting to do so badly what I enjoy doing when my body punishes me for it. I love dance so much, but this pain and fatigue has been really dragging me down this past week or so. I don't want to have to give up my life as a ballerina. I know I'm going to have to grieve this huge chunk of my life soon to find a more healthy alternative for me. I don't feel ready to do that anytime soon. Sorry, it's just nice to get that kind of thing off my chest. I'm guessing I can find some others who relate to me. If anyone has any tips on grieving their past life or even just finding good exercise when living with EDS, that would be great.
