Adjektive

Taking my temperature last night, I had to laugh at myself for feeling disappointed that it was only 100.3, because I felt so much sicker. Now I'm wondering if there isn't one of those wonderful German compound adjectives that describes precisely the feeling of being disappointed that you aren't really all that sick, no matter how you think you feel. And if there also isn't a word that describes the act of bravely soldiering on at your desk, even though you ARE that sick. Anybody? A litle help? Bitte.
