No, I am not thankful for mistakes. I am thankful for the fact that with most mistakes you get second chances. In my case I am talking about weight. Over the past couple years I have gained some weight back, and recently I stopped going to the gym. I tried working out at home but that was not cutting it for me. Well, I have started getting back to the gym and already lost four pounds. So second chances (or third, fourth and etc...)work, so give yourself another chance... Get up and get healthy..
