Hang in there, Thistime!
Don't give up on yourself! You just haven't found the right way for yourself yet. My weight loss plan didn't really click until this year (and god knows, I've been trying to lose weight for YEARS), when I finally discovered what my trigger foods were. What a surprise, actually. I knew that I had issues with salty, greasy, crunchy things but what turned out is that actually I didn't really start craving those until I had sugar and caffeine
Before I found that out, I had almost lost hope. I began to think that I was just a useless eating machine. But after I got rid of my triggers, it was amazing the difference. It took a while, but I began to feel like I could eat like a normal person. I found out that really it wasn't due to my lack of "willpower" but more to a physical addiction. And that felt great! Anyways my point is, it's probably not "you." For me, reading "Why Can't I Stop Eating?" was really helpful. It was because of this book that I was finally able to identify my possible trigger foods.
