9) Many with CFS live in poverty.
A favorite food or a gift certificate to a grocery store would be right on the money. Consider a bottle of omega-3 oil or vitamin D. You'd be surprised what is a luxury to people with no money. Taking them shopping or better yet, doing their shopping for them may be the greatest gift of all. Especially if you foot the bill for some of it. Or all of it.
10) Some with CFS are so sick that almost none of the above applies to them.
They may have to be alone in a darkened room -- if they have a room. They may be living outside. Many do. They're homeless because of financial ruin that dropped on them when they got too sick to work. Or they're so chemically sensitized to toxins in our environment that they can't live among us. They're in the woods, or in the desert, in a tent, a car or a gutted van. They may live this way for days, week, months or years. For some it's decades.
It may seem almost pointless or embarrassing to do something for Thanksgiving for someone in this situation, when their needs are so great. But every contact and every small creature comfort matters. And every reassurance that they're not forgotten by the rest of the world is something more to stand on.
I spent 15 years losing the battle against Chronic Fatigue Syndrome. Three years ago, I found treatment that worked for me, and now I am making a comeback.
