It doesn't sound like your pdoc is going to sign and I'd bet it's well within his rights to not treat you if you all aren't seeing eye-to-eye. You don't have to go to him and he doesn't have to have you as a patient.
I can't imagine why you'd be planning on a psychiatric emergency though that would hurt your health other than suicide. Doesn't exactly go with your protests that you're working hard at getting well. It's not like you can "accidentally" have a psychiatric emergency that endangers your health/life, especially when you're doing okay now and allegedly getting better. I think most DNRs are for heart and stroke patients who could have another heart attack or stroke at any time.
California, of course, is a different Myself:
"If you think you have a MEDICAL OR PSYCHIATRIC EMERGENCY, CALL 911 IMMEDIATELY or go to the nearest hospital. DO NOT attempt to access emergency care through this web site. An emergency medical condition is a medical or psychiatric condition that manifests itself by acute symptoms of sufficient severity (including severe pain) such that you could reasonably expect the absence of immediate medical attention to result in any of the following: serious jeopardy to your health, serious impairment to your bodily functions, or serious dysfunction of any bodily organ or part. An emergency medical condition is also "active labor," which means a labor when there is inadequate time for safe transfer to a Plan hospital (or designated hospital) before delivery or if a transfer poses a threat to the health of the member or unborn child."
