I don't know if it's one of the first things I read in the ACE Instructor Manual, or just one of the first things that really jumped out and grabbed me: as an instructor, it's important that I project a positive body image. Whenever I'm around my participants, I just shut down those negative thoughts. And over time, the thoughts don't come as often, either.
On the other side of it - and not saying that you're even one of these - but there are a couple of instructors at my gym whose body fat percentage is rather high. Before I became an instructor, as a participant, I just loved the way that they projected that someone could be very fit without being a beanpole. And I loved the fact that my gym didn't succumb to stereotypes of appearance.
(((((((Miranda))))))) I know that there are still levels where you love your body. Let your head spend more time on those levels, and less in the destructive places. This is part of your healing from your wreck too, and it deserves the same energy and caring that you devoted to your physical healing.
