Just told my husband. No one else needs to know. This is a private matter. No one needs to know.
I think in general, we feel pressured to share with everyone, friends, family, co-workers. And sometimes we feel the need to share with complete strangers very intimate details of our lives.
My weight and my health are topics that only my husband needs to know about.
If anyone questions my weight loss, I will say , "thank you".
I am not telling my mom, as she will spread it throughout the known world.
Same with co-workers. I work in a relatively small workplace, and word travels amazingly fast.
