I find myself asking the same questions sometimes. Only unlike you prior to surgery I didn't have a bf or kids. I still have no kids, but I have met and gotten engaged to the most wonderful man, so he fills a lot of my time now.
I also go to school part time (although with taking 3 classes it might as well be full time it feels). I still haven't figured out a major exactly, but it's either going to be something with english or nutrition.
Find time to do something for yourself. Do something small maybe like get a pedicure every two weeks or go for a walk.. Take pictures of the beautiful fall scenery. Do something for YOU!
And congratulations on all you have accomplished!
