Motivation and support please....

Hi all,
I desperately need support, please add me as your friend. I recently had my blood sugar levels tested and from the result, my doctor has informed me that I have pre diabetes. I therefore need to change my lifestyle and although I eat healthy (most of the time) and I workout, I think its my portion sizes. Its my first day being healthy and already I have munched on a white chocolate chip cookie. I have no will power at all. Please help by supporting me.

Thanks
Mai
