All I can say you must have have some passion in you life other than nursing.
I practised nursing for 42 years and just had to retire. I am so busy. I work out at least 4 to 5 days a week for 2 hrs, walk my dog, play my guitar, see my grandkids, ride my motorcycle , and in the process of remolding my home. I also love to read, and travel, bicycle and kayak. My home has a garden and that takes my time also. You are now in the adjustment phase and most likely feel like you are not needed. The working world is very demanding and you body is also adjusting. Please give yourself time to adjust. Find some passions in your life and you will wonder where the time is gone.
Best of luck
