What I have lost last Year, I gained all back this Year

What a shame. Last year I tried my very best to loose some weight for which I was successful. I trimmed down a bit and was proud of myself. But December time came. We went through some stress and I have to help myself to get over it. And of course, I indulged with food. Today, I weighed myself on the scales, and presto, there it was, bang right to my eye. I am back to my previous weight! Oh well, it's only the start of the year, I have plenty of time to loose again.
