Do you want to lose the weight?
Are you afraid of failure?
Are you sure you're afraid of failure?
Or, are you really afraid of success?
If you depend on your way of eating, or your extra weight, in any way for any reason in your life, then you may be apprehensive about losing the weight. You may be afraid to succeed.
A common antidote here is to make your own personal list of pros and cons for losing the weight.
In other words, think about what having weight loss success will do for you. Also think about what the extra weight does for you.
It is here, in the conflict between success and failure that you may find the answer to why your weight control problem persists.
