The last time I exercised was in the Outer Banks with my family for my dad's 60th birthday. Not that long ago. My symptoms miraculously disappeared (or mostly) while I was there. Some of us decided to play a little light beach volleyball, just bumping the ball around in a circle. I joined -- and it felt great! Physically I felt strong, energetic, talented. Emotionally, I felt happy, relieved, and a little bewildered. I haven't exercised since then because doctors told me not to. And mostly because I'm scared to. I'm scared I will do some permanent damage, I'm scared it will hurt a lot, I'm scared it will be exhausting.
