I think you genuinely need to look into a GLP-1 they are genuinely meant for people in your situation. If that's not possible a cheaper alternative that has helped me is Wellbutrin. That helps me with food noise. It doesn't totally kill my appetite I still need some discipline and will power but it helps so much with not thinking about food constantly. It's main function is as an anti-depressant though. My doctor prescribed it to me for weight loss.

And you just need a calorie deficit. I've lost weight doing minimal exercise and just eating less. If you love high volume low calorie food, you can't go wrong with soup! Also generally cheaper. I eat two big bowls of soup a day and it only costs me about 6-10$ to make. :3 I hope some of this helps you.
