There's a wonderful site I *finally* found again after losing track of it for a few years which has about a dozen "songs to fight aplastic [anemia] in the middle of the night" at
http://aplasticcentral.com/music/. I had stumbled across it looking for Lightfoot songs and found "The Pony Man" here and includes the "Aplastic Theme" which is John Denver singing "Some Days Are Diamonds" lyrics below:
When you ask how I’ve been here without you
I like to say I’ve been fine and I do
But we both know the truth is hard to come by
And if I told the truth, that’s not quite true
Some days are diamonds, some days are stone
Some time the hard times won’t leave you alone
Some times the cold winds blow a chill in my bones
Some days are diamonds, some days are stone
Now the face that I see in my mirror
More and more is a stranger to me
More and more I can see there’s a danger
In becoming what I never thought I’d be
Some days are diamonds, some days are stone
Some time the hard times won’t leave you alone
Some times the cold winds blow a chill in my bones
Some days are diamonds, some days are stone
