Losing weight sucks

I was a heavy kid and now I am heavy as an older adult. I want to get healthy and I want to live a low carb lifestyle.  I went on a low carb diet a couple of months ago. I lost 30 pounds and my labs looked great. I had been diagnosed with diabetes. I know I can do it again. I started Monday and was doing well. A craving for chocolate cupcakes with butter cream icing tonight so  off to walmart I ran and got 6 ate them. I am like a heroin addict. I need to start, stopping myself, before I  before I get my fix.  Maybe I want to feel helpless like I have no control but I know I do have control. I just need to learn to stop and think before I indulge. I am done with guilt. New day tomorrow.
