So I've had issues with this one coach at my gym for a while. Being disabled, gymnastics is slightly difficult as there are some things I simply can not do. We mainly work around this, but this coach refuses even to try. A while ago, I was on beam when my heart rate got too high, and I felt like I would pass out. I asked if I could sit down and she said no. I went back to beam but then turned white and passed out according to my BFF on the team. Now, at practice last night, a myriad of things occurred. Normally this coach only does my beam, so we work around most things. But my regular coach was out last night, and the coach that was supposed to fill in for her also got sick. So this coach ended up having us the whole time. At the beginning of practice, I was one of two girls that did all of the conditioning all the way without complaining. But we went to vault. Which we weren't even supposed to do on this day. For some reason we do a vault over a block - I am Xcel gold, so I use a table - and I always over-rotate, so I am exempt from the station as I consistently sublux if not dislocate my knees upon landing as I always fall forward. This coach decided I was going to do the station. But this time instead of catching myself with my arms, they would stay by my ears. So I did that. And promptly faceplanted. She wouldn't let me stop though. I probably did this about 10 times in a row before my kneecap ended up on the side of my knee. I had to go wrap it and then I was done at that station. Next, we went to beam. We warmed up as usual - no issues whatsoever. I thought I might finally have a decent beam rotation. I finished everything and was then told to work front walkovers on a line on the floor. Now, I'm not supposed to do skills involving a consistently arched back due to a back injury. But upon hearing this the response I got was, "Well you don't know until you try." So I tried. The first time I did it, there was a crunch in my back and horrible pain. I told her this and was told to keep going. So I did. I did about 2 or 3 more before I was in tears and could no longer feel the bottom half of my right leg due to swelling. Only then did she allow me to stop. I was then told to do handstands. Which I did, but felt it was pointless and I have an impeccable handstand. What do I do? I wrote a strongly worded email to the Xcel director in hopes she can help me, but I don't know if it will work. How do I get this coach to listen to me?
