The only people that I have told at my work are those that need to know. Sometimes I have to miss work to go to the doctor, so I felt that my supervisors should know that I am not a slacker. I also work with a bunch of nurses, and I felt that they should know in case I have a crisis. Most of the other people at work don't really know. Some suspect there is something wrong, but I don't consider it to be their business.
