I can't answer your query really, but I wanted to let you know I sympathise. I did really well on the diet - lost five stone in three months - then had time off for a holiday, which was fine and I only gained a little more than water weight. Then I had a car accident and since then I just haven't been able to get back on track. I'm physically fine, my car is fine, but there was a death involved and I'm not handling it well. I'm so depressed that all I can bring myself to do is eat my feelings. I've stayed away from the board, as I feel like a massive failure, and reigniting your spirits is incredibly hard.
None of this helps you, I know, but I hope there's some comfort in solidarity.
