I think SOMETHING IS definitely in the air for soo many people to have an attack in the same week!!
GIRL, don't even worry about calling in! They don't pay you?? Well, don't worry about it.....they can learn to live without their "unpaid intern" for one day. Don't feel guilty, seriously. But, I know it's hard. I felt really guilty. I don't like to have to continuously call in sick so I just quit and then go back when I am stable enough that I can go a month without calling in sick again. I get the REALLY GUILTY feeling. I hate that....
