Hey Butterfly,
I love that you're so open about your struggles - you make so many of us feel like we aren't alone and that we can say how we feel. Your journal is one of the first I browsed on here and I remember thinking "man, this must be such a safe space because she's so open and genuine - what a doll!"
I was (and still do) run into that same afternoon breakdown where I did so good then BAM, give me food NOW!! It feels like I mess up once and the entire day is ruined so why bother?! I started meal prepping and it does help some. It kind of shook me out of that 'gimme the cookie' mindset and let me see "this is what I'm eating today and that's okay".
The other thing I do now is say "I can have this but..." Sure, I can have 4 tbsp of peanut butter (which is delicious!) but I need to work it off first. It makes going for a smaller, healthier alternative much easier.
The final thing I do is get out. I leave the debit and credit card at home, pack up the kids, and we go for a walk. It's cold, it's icy but I'm not eating and after we get home, it's time to make supper or I have something else to do or that craving has passed.
It's nothing spectacular but you CAN get through this. You've got through so much already - this is just something that is taking baby steps - and you're learning more and more along the journey. Your health isn't just weight or body - it's also mental health. You're getting healthier.
Take care darling!!
