I think you and I have a different view of selfishness and abuse.
I said that I would not agree to a feeding tube for somebody I love. To me that would be cruel, inhumane and selfish.
Let's agree not to name each other in a medical POA. :)
My dad was buried 25 years ago today. I had had to make the decision to not put him on life-support.
When an ultrasound showed "somethimg ?" around my mother's liver and the doc called to have more tests, I said that if she had something I didn't want to know until it caused her a problem because I didn't want treatment that was worse than anything she might have...at her age and with dementia.
Pain management was always my first concern with my parents and I have never regreted those decisions. I wouldn't want to be kept alive just to prolong my life. I'm not afraid to die.
