Has anyone found that the mental side of weight loss is actually harder

I've realised that for me, knowing what to eat has never really been the problem. It's dealing with stress, boredom, and emotional eating that seems to undo all my progress.
I can stay motivated for a few weeks, but then life gets busy or stressful and I find myself slipping back into old habits. It's frustrating because I know what I should be doing, but actually sticking to it long term feels like the biggest challenge.
Has anyone managed to break that cycle? What made the biggest difference for you? Was it changing your mindset, getting support, medication, therapy, or something else?
I'd love to hear what's worked for other people.
