What is wrong with me?

People can get emotionally attached to food. Start by no longer buying junk food at the store. You'll slowly run out of what you have at home. Buy healthier options as well, take the time to prepare meals. Maybe start trying to be more active as well. Exercise reduces appetite. You have to retrain your brain to not always eat.If you think your issues are psychological, see a doctor.

Try to find a different outlet for your emotions that doesn't involve food. It can be something like art, taking a walk outside, or even cleaning. Do activities that make you feel relaxed.
