Does your state not have provisions for suicide attempts? If nothing about attempts is explicitly stated in the legislation, I'd suggest seeing if any cases have been brought to court in your state. In my state, suicidal patients are assumed to not be of sound mind, so they can't legally give informed consent for a DNR. If it's not explicitly discussed in your local laws, it may depend upon hospital policy—which kind of defaults to DNRs not being followed for suicidal patients bc no one wants to put their license on the line for that. Which will be your same problem getting a doctor to sign a DNR that covers suicide attempts or if you have a history of mental illness. It's also important to note that a DNR doesn't mean that a hospital can't treat you. I'm sure you're aware from looking at the laws, but a DNR goes into effect once the heart stops beating or you stop breathing
