Sandy, 12lb in 2 weeks is amazing. Ok this week you feel disappointed, but perspective is needed. In the past I have sabotaged my efforts all too easily by comparing my losses with other people, by being disappointed by sts, small losses, or even gains.
Thinking what's the point, I'm not losing as fast as others or as fast as I want to. The reality is we have to stick with it through good weeks (of which I'm sure there will be many), bad weeks both in dieting terms and life! The alternative is to give up, gain more weight, stay hiding - you are a strong & determined woman & you can do this. You were such a positive influence on me during the first week - I struggled & could have given up completely & you helped me realise that I can do this. We won't all lose the same every week, in spite of our efforts; but we will all get to the finishing line if we really want to.
