I kept it a secret and I am 10 months out. The only one that knows is my wife. I also am a teacher and I know how fast things fly around my building. The funniest thing was the older teachers asking me if I was sick. I even overheard that I was on prayer lists. Its just hard for some people to accept. The ironic part is I was sick when I was morbidly obese but its so common that its viewed as the norm. Even my family doesn't like the amount of weight I have lost. So I do not regret not telling anyone. But its a personal choice and everyone has their own choice.
