I told my boss right away about my diagnosis. He was very understanding, but he isn't the kind of person who would complain about anything.
More problems I have with telling the people I don't know very good; I would't just tell them "Hey, I got MS...", since virtually all the people I told about the MS reacted quite shocked in the first line, although now they got used to it.
Now, most of the time, they don't talk about it, most don't even dare to speak the two words "multiple sclerosis". If they want to ask about my conditions, they just say "and how is THIS?" (as "you know what"). I find that somehow disturbing, but at least, they ask at all.
I haven't lost any friend just because I told them about my diagnosis, but I know some people who have. Thats really bad thing to happen...
However, I really think about whom I tell about the diagnosis. I think, I still have to learn to deal with that. Its still not easy, just one year after getting to know about my ms.
Since I don't have any visible disabilities, its still not so urgent or necessary to explain.
Wish you the best, Antje.
