It's important to say that DSM-V (the new edition of the diagnostic manual) is being compiled in secret, contrary to the open nature of science, and demonstrating that the psychological community are circling the wagons against what is certain to be a storm of criticism once it's published (slated for May 2013).
One of the tidbits that has slipped out of the secret process is that grief over the loss of a loved one will qualify for a depression diagnosis, which will allow the prescribing of drugs to treat this new "mental illness."
