I encourage all caregivers to remember that there is no "one-size-fits-all" approach to providing care. Accept that you will make mistakes. Control what you can control and let go of the rest. You didn't ask for this situation, but you are here and stepping up to care for your loved one. That is an amazing undertaking!
I'm a senior trying to care for an even more senior parent. There are lots of us. We are grandparents who are struggling through our "golden years," some of us still working far beyond age 65. Many of us are trying to be good "children" for our parents at the same time we are trying to be present in the lives of our grandkids. It's a tough, multi-generational balancing act.
