I can so relate to this and I don't feel guilty making the comparison. The only other prior addiction I can personally claim is nicotine, but I've also had close-up experience of alcohol, cocaine and ketamine addictions (as well as "lesser" drugs) through several family and friends, and I'm convinced that to a point similar mechanisms are at work with food. If anything, I've occasionally felt slightly bitter that I don't have the option to go cold turkey, as the substance I abuse, have been emotionally dependant on and has most definitely affected my social functioning more times than I can remember is absolutely essential to my survival
A childish and petty thought, and not one I've ever been proud of whenever it's reared it's head. But it is true - we don't have the option of total abstinence, or of removing ourselves from a life and set of friends who promote a particular damaging lifestyle.
So it's a different battle, but I reckon still a winnable one
Strength and confidence to all! xxx
