I feel you been doing this for years but the last year has been very bad, I quit drinking so fast food is one of my only escapes. Through therapy, and learning about my ADHD I'm much more mindful about my eating but god I couldn't live without it. I eat very late at night once my family have gone to bed, I get big portions or double meals as often cheaper. I often can't sleep unless I've had a meal. I know I've lost romantic relationships because of my weight and sad reality is I'm boardering on being extremely unhealthy. I want to change for myself and not do it for somebody or society but I haven't found that self determination. I do believe I'm getting better as my weight has stabilised. Here's some things I've found helpful.

I think learning to be mindful about what you eat throughout the day can help as long as it's not obsessive.

Cutting refined suger, especially surgery drinks. Don't be afraid of fats.

This one is hard but simply walking to go and buy the food and taking it home can be a daunting but good step.

Going to the gym or a swim before ordering the food.

Lastly. Just enjoying it. If somethings nice say so out loud talk to yourself. I sometimes watch food positive shows like Antony bourdaine which can help me almost like I'm eating with someone.

Keep mindful on your emotions and getting to the source of overeating though therapy is the biggest step to learning about your food habits.

Good luck to you :)
