FRICK ON A STICK.

Today I went to my high intensity step class (an hour and half - usually i love it) but today I had an accident. I slipped off my step and my right ankle got sprained. I was in pain and stopped stepping, we soon did ab work and floor exercises for lower body toning, which I participated in, but about 10 minutes later I looked at my ankle and it was swollen like the size of a golf ball!!

Now I have crutches and have to stay off it for who knows how long. This is making me panicky because:

1. I've never injured myself this bad for anything before;
2. I'm afraid now that I can't exercise, I'll gain weight again and get depressed;
3. I' mpanicking because it's so uncertain as to when I 'll be back up and running.

Im upset about this. Any advice to offer?
