I was recently prescribed prednisone 20 mg for ten days but to stop it as soon as symptoms improved. i took it for about 7 days for bronchitis after covid. since i have stopped i am full of panic/anxiety, loss of appetite, nausea and sweating?

You should be very happy you got over Covid ! Resume normal life and diet gradually, there is little to worry about now. But if you dont feel better after a few days re-consult your MD. Hope you feel better.

Stopping the Prednisone at 7 days is not what is causing your symptoms. It looks like even before COVID 19 infection you might have been having anxiety disorder. The loss of appetite nausea and sweating hopefully resolve in time, however you should evaluate what may be the root of your anxiety disorder because the symptoms may also be part of it. Try and que your brain to calm yourself and rest.
