It sounds like you are in a transition phase of life. You have accomplished so much and are maybe used to being more busy with external things/other people's problems. I am sure your kids will always need you but I know it must be a hard time to adjust to. I hope you find more and more things to enjoy just for you, and find ways to enjoy the expanded space and silence if that appeals to you. Or you could take a class, whatever it may be, the world is your oyster! I can relate to the not wanting to talk about my writing thing, people are so "Show me what you've accomplished" or have so many presumptions about what writing is, it's exhausting and invasive and makes me feel like not a real writer. But it doesn't mean you aren't a talented writer and your efforts aren't worthy. I don't think it comes easily for most of us, to be fair.
