Pat, I don't think anyone can make you stop except yourself. You have to find the way.
When you're really ready, you will make better choices even if they are hard. All of the folks who have successfully lost have made these hard choices, sometimes many times a day. Until you are really serious and really ready, you'll always be trying to cheat the system, and you'll eat the wrong foods or overeat.
You must understand that it doesn't matter whether the Queen of Sheba offers you the last piece of cake in the Universe--if it's not on your plan, and you want to lose weight, then you turn it down. If you choose to eat it, you face the consequences.
Unless someone is holding you down and forcing food between your clenched teeth, you are the one making the choices. You can choose whatever you want--you are an adult, and you have options. If you really want to lose weight, you'll find a way to make better choices.
My question if I were you would be, How bad does it have to get for me to change?
Have you tried counseling? It may be that you have a type of eating disorder. Lots of professionals specialize in food problems these days--maybe you can look into that.
Good luck! We want to see you succeed!
