Fatigue off the scale

Ten years on from diagnosis and fortunately annual MRI scans show condition is stable. The fatigue is getting worse though. Trying to motivate myself is an ongoing battle. Tired of explaining myself. The Oscar winning performance of putting on the smile, being positive and cheerful when all I want to do is shut the world out. Two things I always enjoyed a long walk and swimming. Both out of the question now. My left leg is damaged so I walk at toddler pace. Swimming is a no go due to suprapubic catheter. Any thoughts?
