I don't think my anxiety is all that noticeable to others, to be honest. I also work in the parameters of within a school department and maintaining 'stability' is actually written into all new hire applications. I think that's standard for any school hire. I don't disclose my MS that's in remission nor do I discuss the depression that ties into the neurological illness.
One word that gets tossed out within circles is neurotic when anyone is a bit over the top with expectations but not necessarily towards myself.
I really think anxiety above most anything else is a dominant MH symptom in the field.
