The title of the thread is "I don't get the "anxiety" part of nursing"?
You're telling people not to cry?
You seem a little flippant about the things you "occasionally miss", and perhaps that gives you an edge in the anxiety department. And I'm sure the pills help as well.
In my experience, there are many specialties to choose from in nursing. Being in the one most suited for you will go a long way in reducing anxiety. But, of course, the main vein of anxiety seems to flow throughout nursing and is caused by the conditions and workloads that we continuously accept. If you can't do your job safely, it makes you want to cry. And there's nothing wrong with that.
