Kind of a "yikes" reply, given the "should never require medication". Perhaps we have a different definition of "normal grieving process".
You may not like my reply, but there are psychiatric standards for what is considered "normal" grieving and bereavement. Seeking help from a counselor, psychologist or physician does not mean that someone has exceeded the "normal" processes. But in general only a physician can prescribe psychotropic medication. It is incumbent upon the physician to evaluate the individual and determine if they are outside of the "normal" grieving and bereavement process and may benefit from advanced psychotherapy and/or medication. Then, the patient should be monitored for recovery and, possibly, cessation of therapy and/or medication.
So yes, your definition of "normal grieving process" is likely different than the formal medical definition. But physicians should be dealing with the formal medical definition and that is what should be guiding treatment. The FAA assumes that physicians are following established protocols and guidelines. So when a physician prescribes psychotropic medication for grieving then the FAA assumes that the patient had a disproportionate response to the situation requiring medication. They also assume that if the patient was outside of normal grieving then therapy and/or medication should be initiated with a well documented follow up plan to resolution. Therefore when the FAA asks for the documentation it should all easily be available.
The problem is when a physician does not follow established guidelines and there is no good documentation. Now the pilot is mad at the FAA, but the real problem was likely their own treating physician.
As a corollary:
Say you sprain your ankle and go to an orthopedic surgeon. Instead advising you to follow RICE: (rest, ice, compression and elevation) with slow return to full activity the surgeon decides to operate on you, drilling holes in your bones and affixing plates. This is the kind of thing that should only be done to repair an actual fracture, not a sprain. Then, the surgeon also fails to document the valid reason for the surgery, the type of equipment used, or have you return for any post operative follow up. Do you think that is acceptable?
When doctors play fast and lose with mental health, this is exactly what they are doing. And no one calls them out on it. And the patient suffers.
The FAA is at fault for not having enough people trained to process the volume of mental health related cases. However, the FAA is not at fault for treating these cases seriously and requiring proper documentation. People want to think that the FAA treats mental health differently. They don't. They treat it exactly how they treat physical health. If you have a heart attack you have to actually recover, follow all their guidelines and prove your heart is fit to fly. If you have depression you have to actually recover, follow all of their guidelines and prove your brain is fit to fly.
