not looking good

I tried to run on the treadmill today to test out my foot...its a no-go. I lasted about 3 minutes and knew it wasn't going to work. Then I had a mini-meltdown and decided I would try one last time on Saturday. Really though, I already know that I probably won't be able to run on Sunday. It is SO frustrating and disappointing to train for so long and not be able to finish what I started.
