Weight just a minute!

So... I finally decided, with the push from our health insurance,to work on being healthier. I joined Weight Watchers and have made a real effort to begin an exercise routine... however, while doing my first yoga class, I twisted funny and hurt my back once again. I feel so dumb and am frustrated with myself. I know that it will heal, as it already is starting to feel better, but it is difficult to have to cut back on my activity already. I lost 7 lbs my first week at Weight Watchers, injured myself the beginning of my second week and gained back .6 lb. I know that isn't that big of a deal, but the goal here is to go down each week. My dad has lost nearly 45 lbs in 16 months and I hope that I can do as well as he has. I had to write this all out so that I can get over myself and get on with it. Wish me luck!
