The deal with "body image work" that we all need to get hip to, and that I hope mental health professionals will discuss with their clients in more depth as time goes on, is that loving our bodies as they are today requires a commitment to being proudly ourselves in spite of potential judgments by others.
Stress eating happens for most of us, given the right circumstances. Even people who don't usually struggle with overeating turn to food when they're overwhelmed, overworked, or overtired. It's complicated, because when you're stressed, you don't have a lot of extra bandwidth to problem solve -- and your willpower and discipline are probably in short supply, too.
If you are constantly criticizing your actions and hating your behaviors, you're judging yourself. When there's judgment, there's no room for learning. You miss whatever the lesson is trying to teach you. It is these lessons that often serve as our biggest opportunities to see where and how we need to change.
When you're struggling with food or battling your weight, it's easy to self-sabotage. With constant self-criticism, berating our bodies, and punishing ourselves for things we did/didn't do, we often become our own worst enemies. But the things we are telling ourselves (subconsciously or consciously) can do us more harm than good.
