Im wondering if its just me?

Loads of people now are commenting on my weight & are quite surprised Im not going to classes. Id started saying that I was doing it myself with the help of a weight loss forum, but then people started asking 'Oh which one' and commenting it sounded a great idea.

I got very evasive and non commital. I dont want my colleagues from work coming on here and reading my diary & seeing a lot of my posts! Is that really selfish? Should I be helping them regardless??

Dont get me wrong I actively encouraged my best pal to join & my closest friend has the URL of my diary and he reads it regularly. I just dont feel comfortable having my colleagues and acquantances coming on here and seeing me 'laid bare' so to speak.
