Overeating

I go on diets and am determined to stick with them. Well a few days into it I always cave and go on a massive eating binge. I’m an emotional eater. Always have been. It doesn’t help that I’m around food all day at my job. I need help but I’m not sure where to go? Has anyone here experienced this? Please don’t be hating on me I feel bad enough as it is. How do I overcome this?
