Go get assessed and see if you do have ADHD, OCD or something else. If you have ADHD then a lot of the 'dopamine seeking' behaviors make a lot more sense and medication can actually help reduce your food addiction and general addiction susceptibility. If you are a girl, and/or the non-hyperactive type of ADHD and a smart kid, it can be fairly easy to be overlooked, since your 'doing ok' in school, even though it's your intelligence just papering over that fact.

Another way to go cold turkey is to ban all 'junk food & carbs' paraphernalia and just go whole foods / non-processed veggies and meat.
