I'm 42 years old and am starting nursing school in January. Am I selfish to go back to school now? I know I should have done it before kids and now my kids are 12 and 14. I feel like I need to be here more than ever for them but I'm single and am trying to make a better life for us all. I have discussed it with them and they are okay with it but I'm not sure that any of us know how much time it is going to take away!
