Gosh,
I'm so glad to hear you were able to keep your secret!!!!!!
I plan on doing the same thing as I know people in my life (even work) will absolutely flip out! I would NEVER hear the end of it.
I am taking sick leave so I have to inform HR but they can't legally tell anyone.
I have 1 friend who went through it two years ago but she got the DS - so I will share my thoughts with her - as I'm keeping her secret as well.
