Begley in Newsweek: "Get Shrunk at Your Own Risk"

But everyone will experience grief—and counseling for normal bereavement may not always be benign. A 2000 study found that four in 10 people who lost a loved one would have been better off without grief counseling (based on a comparison with people who were randomly assigned to a no-therapy group). That was especially so for those who experienced normal grief. In that case, counseling sometimes prolonged and deepened grief, leaving more depression and anxiety than in those who worked through their loss on their own.

I haven't found the need for grief counseling for myself, despite the automatic recommendations made by a number of people withing the weeks following Avi's death.

I'm familiar with grief counseling and I've made use of a manual on the subject. My attitude is: I'll define for myself, and not let others do so, what is "normal" and "appropriate."
