The heading pretty much says it all. But you have all been wonderful and deserve a lot more than that. So here is what I have to offer:
I've realized that I'am unable to do V.T.
I'm also unable to explain the reasons to people who don't have a chronic debilitating illness any better than I can explain what it's like to lack 3-D vision to people who have it.
The best I can do is to say that doing V.T. is, for me about like trying to catch a flying object (and possibly more dangerous).
I've lived all my life (nearly 60 years) without the benefits of V.T. I can continue to do so for at least the foreseeable future.
Especially since there's still lots of other good things in my life to enjoy.
So I wish you all the best. (And who knows I might be back someday. Stranger things have happened--even in just my own life.)
P.S. Apologies to those who got this on the Groups section. I wanted to get this out to as many of the wonderful people here with whom I've had contact as I could.
