What is proposed for the D.S.M. 5 is a radical expansion of the boundary for mental illness that would cause psychiatry to intrude in the realm of normal grief. Why is this such a bad idea? First, it would give mentally healthy people the ominous-sounding diagnosis of a major depressive disorder, which in turn could make it harder for them to get a job or health insurance.

Then there would be the expense and the potentially harmful side effects of unnecessary medical treatment. Because almost everyone recovers from grief, given time and support, this treatment would undoubtedly have the highest placebo response rate in medical history. After recovering while taking a useless pill, people would assume it was the drug that made them better and would be reluctant to stop taking it. Consequently, many normal grievers would stay on a useless medication for the long haul, even though it would likely cause them more harm than good.

The bereaved would also lose the benefits that accrue from letting grief take its natural course. What might these be? No one can say exactly. But grieving is an unavoidable part of life — the necessary price we all pay for having the ability to love other people.
