Thank you for sharing your experiences. Whilst you may be just starting to get to grips with tackling your binge eating, it sounds like you are incredibly self-aware, and I think that's a huge positive step. I think people have already given some really great, compassionate advice in this thread, but I also just have a couple of small things to add that may help you, as they helped me.
Firstly, I always write a list when I go grocery shopping. I buy only what is on the list, and nothing more. It means that I find it way easier to control what I buy, and don't find myself lured in by offers on big bags of crisps or biscuits. It also means I save money! This way, if you feel like it, you can also plan in a treat if you fancy it (e.g., a packet of crisps, an ice lolly, etc). But you can buy those things in a more controlled way when you've thought about it beforehand, and planned when you want to eat it (e.g., save it for a particular occasion).
Secondly, I find actually pausing just for a matter of seconds and looking at the food I'm about to eat really helps, if I'm about to binge. I found it very hard to do this initially, but often I get to the stage where I've grabbed some bread out, grabbed a knife and some butter, and then I stop and I force myself to think "do I really want this?" and "am I actually hungry?" and "if someone saw me eating this, would I feel ashamed or embarrassed?". Usually those sort of thoughts help me decide whether I actually want to eat what I'm about to indulge in, and 9 times out of 10, I decide not to eat. Bread used to be my real weakness, when I was a teenager and home alone after school before anyone else got in, I used to toast four slices, put a huge load of butter in the microwave, melt it and spread it over the toast. It makes me feel pretty sad at the way I treated my body, but also it makes me feel good and stronger to reflect upon that now, because I can't remember the last time I did that - years and years ago.
Thirdly, I found this is a sort of continuation of the second point, but just listening to my body helped, particularly in the early stages when I was still binging fairly regularly. I'd really pay attention to the bodily sensations I had (e.g., unpleasant taste in my mouth, uncomfortable feeling of satiety, etc.), particularly after a binge, as well as the mental symptoms, and I'd write them down. I'd also focus on the bodily and mental sensations I'd have after not binging. This really helped me to break habits and reflect more on the process, which I think really helped me get things under control.
Wishing you all the best with your plan!
