My DD9 is also not very coordinated and dislikes sports. We have a family rule that she has to participate in something physical. Otherwise, she would sit on the couch and read all day and night. She tried soccer, gymnastics and dance-- stuck with each one for a while but never quite got the hang of any of them. But now she is into Zumba (of all things!). It is not competitive, but it keeps her moving. We do it together (the place near us won't allow kids without an adult) so it's mother-daughter bonding and she says it makes her feel stronger. This might be something you could try. I also second the poster who mentioned horseback riding. We have a friend whose 2e daughter is a great experience with it. She helps to care for the horses, learns to calm herself and focus.
Something else to consider . . . has your DD ever been taught any relaxation techniques? When things get too intense, this can help them to relax and let go of some of the intensity. My kids love tapping therapy. I thought it was nuts at first, but it truly does help them to calm down and focus, especially when they are upset. (No idea if there is any scientific reason this works. I don't even care if it's all in their heads, as long as it helps them.)
