@lisadiane, yes fear of recurrance is completely normal. It sounds like your profession as a fitness instructor has served you well, keeping you strong physically and likely mentally as well. The fatigue must be frustrating. It's so hard to explain cancer-related fatigue to others. Everyone is tired these days, but this fatigue is different. It's like you're weighed down by a suit of armor with cotton wrapped around it - heavy and foggy at the same time.

As you push through the fatigue to teach, do you find the physical activity helps or do you crash afterwards (or both)?
