Renerian..
Perhaps you just need a "time out"...
Might do you some good to do sth. entirely different for awhile and "get away from it all"... do sth. totally mundane.
May take a year, may take more.. then again, may take only a few months. But you'll at least be removed from the scene to be able to think clearly and sort things out for yourself.
If you're meant to continue nursing, you'll sure know it.
Wish you the best in whatever you decide ! Take it easy for awhile, ok?
