Yes, well...perhaps those criteria need to be reimagined.Like for physical illnesses euthanasia requires you to have two doctors state that you have zero chance of improvement, and it is life limiting (and tbh in most cases most docs wont unless it's terminal anyway). And I'm not sure PTSD would fit criteria for the (vast!) majority of folks, because treatments exist and can be effective
And, while treatments *can* be effective, they aren't always.
I hear what you're saying. Will likely never happen because of the current way people are taught to think about mental illness. Which means those people who want to die will simply kill themselves or live their lives in misery. I personally don't think that's the better option. But...*shrug*
