I've in my late 20s, size 18-20. I was a size 10/12 until I went to university and was very unhappy, anxious and depressed there and I've been a size 18ish ever since. I comfort eat every evening, I've tried to replace it with yoga, walks, journalling but none of it feels as comforting for me. I've tried counting calories, intermittent fasting, trying to eat 'normally' (i.e., 3 meals a day). I'm coeliac so I can't eat gluten which has cut out lots of cakes, biscuits, doughnuts, baguettes, etc. I just don't think any of it works, at least not in the long-term. I remember sitting in a nutrition lecture at university, and the lecturer saying diets don't work, and the scientific lecture supports that as most people regain the weight they have lost.
I'm so angry at myself that this will yet again be another summer where I'm wearing jeans and long sleeves in the 30 degree heat because I'm too insecure. But AIBU to think there's no point in even trying with dieting?
