gotta love a person who admits she has a "short fuse and a hot temper"! i'd suggest you make an appointment with a medical professional for a physical examination. when you push down on your shin bone and the skin stays indented that is a sign of fluid retention in the legs. this symptom combined with your shortness of breath warrants a check-up. it might just be that you need to cut back on salt. but it could also be sort of an early warning sign of additional heart problems (besides your mitral valve regurgitation). it wouldn't be a bad idea to get this checked out so if it is something with your heart you've caught it early. wishing you (and your temper) all the best! sounds like fluid retention. i have the samething all the time nearly.
