“I am a researcher in caregiving for hospice patients- but more importantly I am a
caregiver for my husband who has Stage IV head and neck cancer and who has
just recently completed chemotherapy. Despite my years of hospice practice and
my years of research on this very topic- I was still unprepared for the impact of
this on my world. I am better educated, more financially secure, and have an
outstanding support system and it still has been the hardest 6 months of my
life.”
“I work with physicians everywhere in my department, amazing family physicians,
amazing palliative care physicians- and yet- the focus of all concern remains with
my husband- and I’ve been surprised with how little any professional really
wants to hear about how this impacts me.”
“The official and unofficial health care teams simply do not acknowledge the
caregiver. I believe that is in part because it would be so hard to really
empathize as the pain of it is just too great.”
