Sing in a choir. Volunteer at the hospital, at the senior's center, at the library, at the soup kitchen, or at the school. Find something intriguing to do that will make your daughter proud of you, as an individual doing interesting and worthwhile things, not just as a doting mother. What I'm saying is that you must face life without that child under your wing because her childhood will not last forever. In fact, it is over right now.
Life is a lot more than just raising a child.
I wish you many more years of a different sort of usefulness.
