My anger, resentment, whatever you want to label it comes from the fact that I've been there for Mom and Step-Dad for over 10 years. I have a good recollection of their health histories for that reason. Mother has asked and legally given me Power of Attorney medically and financially.
Mother is recently diagnosed with lung cancer. The 2 absentee daughters are now ever-present and are going to take care of things. I'm being called "controlling", "stressed" and told to step aside.
I'm trying to let them do whatever, assuming they will eventually fade into the woodwork, while still being present at appointments to catch information I could need to know and taking care of the things they aren't catching or doing.
Yes, now I'm stressed, but not due to the parents, because of my siblings.
