Are you?
The symptoms are a kind of malaise, feeling not depressed, just a bit low. A lack of energy or enthusiasm as in not getting your hopes up too much. In case you get disappointed. Again. A friend cancelled an outing, the weather forecast said warm and sunny and it was cold and wet, I was planning a long awaited trip to the city and they reinstaated restrictions......and so on. Nothing too serious but a kind of weary resignation was my response.
A loss of joie de vivre might sum it up.
Those are my symptoms, yours may well be different if you think you have this condition that is.
I write from an area with three cases and zero deaths and can begin to think 'post-pandemic'....
