I am getting my sleeve July 27th in Mexico. I've only told my kids, parents (don't know it is next month, just some time) and my 2 sisters. When I reach my goal weight, I will proudly tell anyione that asks, especially another overweight person, Firstly I am a very private person and secondly, I dont want the added pressure and thirdly ultimately this is my decision.
Good luck to you and if the decision doesn't affect them personally it is none of their business.
