In reply to mypyrex:
It's not just you and you're quite entitled to judge them based on their non-involvement - real friends (and decent people who are mere acquaintances) make the effort. It's not a reflection on you, either - most of us, particular in this era of social media 'friendship', have a few very good, proper mates and a lot of fair weather dilettantes, on whom it's pointless to rely. I tend to let these go sooner rather than later. Tellingly, some of my best friends live in other countries, or even continents.
My mother-in-law died over the course of a decade or so, of a slowly progressive paralyzing condition. For the last 5-6 years, she was unable to leave the house. Her best friend abruptly stopped visiting at about that point, without explanation. That was pretty awful in itself, but worse still was her insistence, whenever my wife and I were visiting, to stop us in the street simply to tell us that she *wanted* to come over, but it upset her too much. My wife refused to let me tear her a new one, but even now I have to resist the urge to jump in the car, drive 300 miles and explain to her what a miserable excuse for a human being she is.
<phew>
That said, hope you're doing OK and that getting off the cycle of chemo is helping you to feel better. Post-recovery, if you feel like a jaunt to Cornwall, at whatever grade / length of walk, let me know.
