Responsability is not only a requirement for nursing but also for everything in your life as an adult, if working as a nurse made you feel that is too much I think that you can think again alone reevaluate your goals, forget about family and ask yourself What I want to do with my life? I want to work with this people everyday? But the most important question you need to answer is about your patients they deserve the most qualified care and not only a very skilled nurse and if you don´t feel good doing this please don´t do it, stay at home and enjoy your life.
