2 years ago my DH & I decided to go full-time. In August 2012, my father had a very bad fall off a ladder. I moved home with my mother & ended up staying with her for 2 months. Once dad was transferred to a rehab unit, I moved back home to our RV. It was getting close to the time for us to head south for the winter. I told mom that if she wanted we would winterize the RV & stay as long as they needed us. She said "No, you need to live your own life. Now is the time for our friends, who have been offering support, to be there for us.".
We talk regularly, email every couple of days & if there is a disaster, I can get a flight & be there in less than 12 hours.
I am glad you have decided to go. Life is uncertain & you need to live your dreams while you can.
