I'm sorry, but you clearly have absolutely no idea what it's like to suffer from low self esteem and feel a compulsion to 'comfort eat'. Then your weight increases and your self esteem plummets even further.
Most of us now know better to tell a depressed person to 'snap out of it', as a PP has already pointed out. Well, telling an overweight person who is depressed and addicted to comfort eating to just change their eating habits is equally a waste of breath, as it's just not possible until they're ready to face it.
I've been there, as a yo-yo dieter, who is also depressed and suffers from MH issues. I'm overweight at the moment, size 14/16, I know I could do with losing weight, but to be frank, my weight is the least of my problems right now. I have complex PTSD because of childhood SA, waiting for therapy, and I also have 2 adopted DDs of 9 and 6, DD1 has a lot of behavioural issues due to Attachment Disorder and probably being on the Autistic Spectrum, and waiting for play therapy.
My DDs are not overweight at all, I make sure they have a healthy diet. But I definitely don't want them to get the idea that they're self worth is to be found in what they weigh. They already worry about looking fat when they don't have an ounce of fat on them (I blame Barbie and Disney princesses for this).
