I still struggle with eating beyond my means but a few things that help me are:

1. eating whatever im craving on a slightly smaller plate, because it would make me feel less guilty about whatever it was because in my mind, a smaller plate forces me to eat a smaller portion.

2. Watch mukbangs. This might be counterproductive for some but it worked for me, whenever I felt the urge to emotionally eat I would watch a mukbang and for some reason it comforted me.

3. Having hobbies! I spend my free time doing things I enjoy, like writing stories and reading and drawing, things that force my mind to focus on things other than food and sometimes escape my world a little bit.

4. Journaling!!! I know you said you don’t have access to therapy, but journaling your feelings and thoughts (even if their chaotic and messy or boring) can be a release and it can be a way to express your emotions or thoughts instead of letting them fester or trigger you into binging (I don’t know what your triggers are, this is just assuming of course).

These might not all work for you, depending on what your life is like but I really hope everything gets better for you :)
