The stories all seem to be the same, your friend gets the flu. You get the flu. Your friend gets better, you get better. Then you get sick again and can’t kick it. You think it might be depression, but you still can’t shake it.
Eventually, you go to the doctor and you find out you have chronic fatigue. And then you have to figure out what that means…
Some event in your life triggered it, it may have been the flu, it may have been stress, or as I fear, it may have been weight loss and exercise. 🙂
(In my case, my friend got sick again and so did I. Only he eventually got over it.)
