I think it is time for you to take some time for yourself. Schedule a spa day and leave DD with DH or call a girlfriend to go out with or just go window shopping or to a museum by yourself. I know it easier said than done. I hardly ever take time to myself and if I do it is usually for a hair appointment and then I rush home to the kiddo, but last Saturday I went off with a girlfriend to have lunch and a movie. It was nice and rejuvenated me.
