Reading your post, sounds like chronic obesity or at least chronic overweight status describes you well. Medical treatment for a chronic condition isn't failure. Even calling it that, so what? You've already said something needs to change.
You mentioned trying everything, but the piece that's stayed out of reach is a lasting lifestyle shift. Sure, other factors matter, but sustainable loss generally needs a real deficit plus activity. For chronically overweight people though, that's rarely simple.
A GLP1 isn't magic. It's a tool for rebalancing appetite hormones and getting insulin resistance under control. Plenty of people carrying obesity have genuinely abnormal hunger biology, elevated leptin and leptin resistance being common examples. Maintaining a deficit while leptin's abnormally high is basically fighting upstream constantly. Body and brain both insist more fuel is needed than actually is.
Seeking a physician who pairs treatment with nutrition support is worth it.
