So... I went, I got weighed and I breathed a sigh of relief!
4lbs off for my first week!
I was super nervous while waiting to be weighed, my hands were shaking. Then when I finally did and I looked down at the scales I felt so relieved. I wasn't super happy at first... Not that I was unhappy, I was just wondering how great a 4lb loss was, but then I totally realised it's great and now I'm really happy!
