You didnt ruin your life! We are all where we are supposed to be whether it is healthy or not. I hope your dr was just teying to get your attention. Sugar and flour are my downfall, cant stop once I've started, so I need to stop because I want to be healthy and off the binge/purge wagon! You can do it.

It is good you acknowledge you have an issue and are seeing a doctor. Sugar is something you crave the more you eat the more you crave. What about natural sugars in a fruit smoothie, small banana, kiwi, berries and all with yoghurt and trim milk in the blender. Maybe find a focus that involves no thought about weight, like a hobby that is active to get you out of "boring". 18 is such a wonderful age if you let it be. I think there is an incredibly high percentage out there who regret not making the most of those years. If only the stuff I am into now I got into back then. Are you outdoorsy? There is so much choice and getting out there and getting active strangely gives us energy. Good luck
