A very rare disease found in 4 of 1000 adults, and an even smaller margine in adolescents. This illness is developed in very non-active persons who usually are afraid of the world around them. The disease was discovered by Dr. Adam Tack (1992-2007). He was the very first human to develop this illness. There is no treatment. Whoever is diagnosed with this illness will be given a time frame of 5-12 months to live. Side effects include having no friends, being fat, being gay, and going to a catholic school to do crystal meth in the bathrooms. God rest the sole of anyone diagnosed with Chronic Fatigue.
Adam Tack thinks he has Chronic Fatigue.

Whoever came up with this name should be shot. The term 'chronic fatigue' doesn't do justice to this illness, which is much more akin to late stage AIDS than how you feel after a really hard workout.

CFS is a lot of fun because
1. doctors think you're full of shit
2. everyone else thinks you're just lazy
3. no one's bothered to invest in research for a cure, probably because CFS patients are too sick to get out of bed to stage outrageous public funerals, etc.
stuff people will say to you if you have chronic fatigue syndrome:
"it's all in your head"
"you have mental problems"
"at least you don't have cancer or anything. you're not going to die." (false. people with cfs do die. mostly because they kill themselves, but also because they overexert themselves, and their body gives out on them. I myself have very fond memories of being stuck, spread-eagled on my kitchen floor, unable to move).
"but you seem okay"
"let me prescribe you some prozac."
"you need to get off your behind and do something."

Indeed, no condition is a better breeding ground for bitter cynicism towards the rest of the human race that cfs. I get new reasons to hate people every day!

Being sick all the time for no discernable reason. Like, fibromyalgia, but more tiredness and less pain. Typically it's really hard to get people to believe you, especially doctors and social security.
I have chronic fatigue syndrome. Although I'm 22 years old, I still have to live with my parents, who seem to think that my illness is something I made up just so that I could drop out of university and pop pills all day.
