Consider if you are eating enough. Do you find you might be holding your breath when you think about the diagnosis? ..it happens.
I was a mess and just took time off work as I needed to just stay home and rest and cry as I literally couldn't sleep.
Stress can cause all sorts of physical symptons. Other than that you might need your blood pressure checked and blood sugar. If not eating and drinking enough it can cause these symptoms.
I had shaky legs and felt very weak post surgery which I thought was stress but it turned out to be a recurrence of Graves disease ...hyperthyroidism. The symptons were very similar and I probably had both stress and illness.
Keep us posted and take care. Kath x
