It's a lay-on-the-couch-under-blankets-and-self-reproach-and-watch-TV-all-day kind of day. There's just no rhyme or reason for why a person can feel okay one day and like they have the flu the next with this disease. Another day of scarce work lost. I hate cancelling on people. To the world it must look like I'm unreliable or that I just don't care, but in reality it's a blow to my self-esteem every time I have to make the decision to let someone down.
