Well it can happen, and there are tons and tons of reasons that thankfully don't happen to a large percent of the population. I personally have an auto-immune disease and some chronic conditions that combined to create a really nasty soup of general ill-health. I have my good days, but then I also have my bad ones. There are no easy answers - there aren't even very many hard ones. We keep on searching out doctors and fixing everything we possibly can as we identify new issues.
The point of this post isn't to ask for sympathy... but rather to answer some questions that I know some of my bloggers have been wondering. Yes, I do get sick a lot. Yes, we are doing everything we can to get me well. No, I'm not dying. Yes, it's a hard lifestyle but I've learned to cope about as well as a person can. And I treasure every day of good health that I'm allowed.
We don't use the word 'invalid' anymore. It's become almost obsolete in our day and age. I think part of it is that it's associated with a general giving up of ever hoping to become well. Which isn't strictly true, but there are just negative connotations to the word. But the fact remains that even with modern medicine, there are still those of us who are pulled down by physical ill-health. All one can do is pray for relief and acceptance, seek out ways of healing the body, and use every good moment wisely.
