@DoubleBusy2026 You sound very similar to another poster who posted recently, and I wonder if you’re expecting the medication to do most of the heavy lifting for you.
From what you’ve described, your relationship with food sounds like it could be quite disordered. If you want to give yourself the best chance of success, you will need to work on this alongside the medication. Rather than focusing on your parents or WW2, try to focus on what you can do now to move forward.
Start by educating yourself about nutrition: calories, macros, and how to work out appropriate calorie deficit, protein and fibre targets for your needs. Then think about how to meet those targets consistently throughout the day, rather than relying on one binge meal.
It won't be easy, start maybe with a protein yoghurt for breakfast, a small bowl of soup with lentils and meat for lunch, then a calorie counted protein focused main meal in the evening until your body gets used to eating regularly again.
Keep an honest, detailed record of what you eat and drink, including oils, snacks, treats and anything else that can easily be overlooked.
Track your progress consistently. If you’re not seeing the results you expect, review your tracking, perhaps try to drop calories a little further, but not too much. If you do this and still don't lose weight speak to your doctor. Bringing your food records/app will help them to offer appropriate support.
