A new WebMD survey finds many people are experiencing grief for more than a year and that losing friendships can cause intense grief similar to when someone dies.
The sadness and other emotions you experience with grief can have a physical effect on you, too.
The WebMD survey, "Grief: Beyond the 5 Stages," was done by AmeriSpeak®, which is funded and operated by the independent research institution NORC at the University of Chicago.
