I'm in the same boat as you. Make sure you are practicing self-care, that helps me a lot. I keep a journal where I can safely vent, here too.
Even though our children don't live close by, I gave them blank books customized that are titled, 'Questions for my Dad'. I let them know they should start writing down things they want to know from him, while he can still answer. He responds when they share the questions with him.
My hobby (baking, and watching baking shows) helps relieve stress, too.
