Those trigger foods have brought you nothing but misery. This is so reminiscent of my Intuitive Recovery course, in that it is the inner brain (the part that makes you seek food, warmth, etc and find them pleasurable, to survive) that you have trained to seek chocolate, cakes, etc too. You must be firm with it: every time you have a craving, say, 'I know what you're up to and I'm not even going to debate with you, go away!' It will get easier and eventually your inner brain will shut up. The stress you feel around those temptations is created by you wrestling with yourself about succumbing/resisting. Succumb and the stress goes away, but resist and it will go away too.
Think about it. There are plenty of people who lead perfectly happy and fulfilled lives without chocolate, etc. They are not impoverished. You can, no, will do it too. It is natural for the certain knowledge that you will not eat those things again to leave you feeling empty. You may even mourn (as I said in an earlier post). But over time you will regain your equilibrium and sooner or later you will find other things you can enjoy. The freedom to bend, stretch, move, feel confident is so much more worth it than the freedom to eat crap.
Lecture over! Very well done with the gym, Trudy. That fills a space and brings its own feelgood factor, quite apart from helping with the weight management. I'm just getting back into it too. We need another exercise thread! xx
