Caregivers live in the shadows.
The attention of family and community is on the soon-to-be-dead-dude, and the caregiver generally gets a pat on the back, and "that must be rough (and better you than me)".
A caregiver gets sick, and expects of herself a quick recovery, to be back in harness soon.
The person becomes the role, and that's unfair.
YOU are important, for yourself. Your health is important, not because it has an effect on caregiving, but because it has an effect on your life, your happiness.
I am the dying dude. Please trust me on this...as I fade, I want my wife to bloom. I want her to be healthy and happy, and NOT to feel forever defined...and having her 'after the battle' life diminished...by this experience.
And one cannot, and should not compare pain. A stubbed toe hurts. It doesn't hurt as much as pancreatic cancer, but the latter simply isn't accessible to the caregiver.
But the toe, nail crushed and bloody, still hurts.
And it is my privilege to try to kiss away the pain, because it's real.
And it affects the person I love more than anyone.
I don't want her to hurt.
