I'm so sorry you are trapped in this vicious cycle and for such a long time. I can understand that it must feel like an impossible battle. I do respect your wishes should you decide you want to ctb but I wanted to share some of my thoughts and experiences in case you decide to keep going.
I've never actually been diagnosed with an eating disorder but I would say I do have a very poor relationship with food and I am extremely prone to the urge to binge eat. My diets have frequently been obsessive- one way or another.
I do understand and deeply sympathise with how hard it is to overcome the urges to restrict or binge. However, I do firmly believe that restricting LEADS to binging. I'm so frustrated that I can't find the reference now but I'll try and summarise what I learnt- we are still very much influenced by the primal side of our brains. When we restrict food, our brains believe we are starving- they don't see it as a choice- they simply think that food has become scarce. So, when we start eating again, we become overwhelmed with the urge to eat as much as we can- to get us through the next period of starvation- should it come along.
I do completely get that a period of restricting sometimes happens as a kind of guilt response after having a binge but I think it helps to understand some of the psychology behind it- that you're not weak for giving in to a binge- you're having to fight off your primal brain that believes it is in a fight to keep you from starving and dying.
Therefore, if you possibly can, I think the initial steps to break the cycle are to try to stop yourself restricting in the first place and to allow yourself to eat- even- and especially following a binge. I think the urge to binge will still be there from time to time but hopefully, not as strongly.
I actually lost 5 stone following a no sugar and low carbohydrate diet for 2 years and, after about a month in, a lot of the cravings for junk food had gone. The food industry are quite frankly monsters in my opinion. They deliberately overload our food with sugar and salt- which make you crave more. I found it helped me to cut down as much as possible on these processed foods.
I have put most of the weight back on now unfortunately and I still don't have a great relationship with food, although it is a little better than it used to be. (Slightly less obsessive at least).
I really sympathise with your struggle and I hope you are able to find peace.
