Fair, mental illness is a sticky subject, and it is tragic when a temporary condition ends in a permanent solution. I do think that it’s possible for a person of sound mind to simply not want to continue living, and that person shouldn’t have to resort to private and illegal, possibly ineffective, or disastrously injurious methods to accomplish this. Personally when I’m elderly and losing effective management of my faculties I’d like to die peacefully and painlessly surrounded by loved ones at a place and time of my choosing, without a diagnoses and a hospital bed.
