It would make sense to binge when depressed as your body needs serotonin.
Bingeing usually falls into the category of carbs which help provide serotonin. Best is, if you "binge" on high quality, whole carbs- balanced with good protein and some fat. Also, exercise will help provide the brain with a good "high." Of course, all of this is good on paper, but harder to do when in the depths of depression.
But having a prior plan may help.
I wish I'd understood this as a teen when I was a very active bulimic!
