It’s a mindset. I was in the same bad ha it’s for like two years it seems. You have to be ready for the change. I’m a total type A so I will get a notebook and map out my plans, my workouts, my rewards. I’ll create rules for myself- things like don’t indulge alone, no soda for three weeks and then you can have one, no slurpies except at the movies. Have you considered exploring the cause for the overindulgence? Coping skills? Clean plate syndrome-as I call it? Scared of failure? I will say that I started doing keto, (I say it a lot in my comments on here lol) but I’ve been using it to identify and work through my food issues and it’s incredible what one month will do for reflection and self control. Just don’t give up on yourself. You deserve to love yourself.
