I think I keep to myself because, in the end, no one can really understand what I'm going through, unless they have/had cancer also. And even that brings with it a range of experiences, the worst of which I'm sure I haven't even touched.
I don't expect anyone to understand, but I don't have the energy either, to convey anymore about it, nor do I think folks really have the interest or attention span. As an example, my friends in southern Cal think I'm flaky, because I may say I'm coming down to visit, and then I don't. It's always been touch and go for me, I was always more mobile than most people I know, but the touch and go of the present has more to do with an illness that manifests differently each day, and the fact that I need to work around my husband's impossible schedule. His schedule in the military was more predictable. I have an aging pet in a house we've been in for merely a month. Someone needs to be around. Or, I could wake up and feel crummy. Not a good incentive to make plane reservations. The will is there but the body rebels. Lest anyone forgets, I still have responsibilities. Having cancer does not equate with being footloose and fancy free.
