Don't be hard on yourself. You can be successful, and you will be successful. What has helped me so much is to keep a food journal to help remind me that I must make healthy food choices to be healthy. Take it one day at a time.
I had stopped losing too. I continued to follow my diet and exercise and than one day when I least expected it, I started dropping pounds again. I dropped 5 pounds within 2 days. Do not give up those pounds will come off.
I would go and have a plate of food that I would carry around and than put away. If anyone ask me why I wasn't eating I could honestly say I just put my plate down, I am finish.
I need to remember to drink water. Right now I am retaining because I have barely been getting 16 oz a day, and the scale has stalled. I hope once I increase my water I will start losing weight again.
