Every one has their own preferance! You shouldn't feel embarassed or ashamed that you are taking control of your life and taking the next step to living healthier. I was very open about what I plan on doing and I got some positive and some negative feedback. I did it mainly for the support. Knowing that people are there for you no matter what happens takes a little bit of the stress and anxiety off. I think you are brave and no matter which way you go, will do great! Maybe consider talking to a spouse or best friend, just that link of support can make a world of difference!
