Well, I own a salon and spa and I told my staff. I had 2 give me a hard time about it, but it didn't bother me. My thought about what people say is, they are concerned for you but they haven't lived in your body and going through this process is not done without a lot of research and deep thought.
Most people will be supportive. Feel good about what ever decision you make, their input won't really matter in the long run. For me it has been the most healthy decision of my life and I would do it again and again.
Good Luck!
