Some do benefit from an antidepressant to get them through the acute phase of loss. Also remember exercise, vitamin D, sunshine, music (NOT sad music!) can all help as well.
I personally love the movie She-Devil with Roseanne Barr - a satisfying story of a woman dumped by her husband for Meryl Streep's insipid romance-writer OW. She gets her revenge in ingenious ways. NOT that I am suggesting trying for revenge - but it is satisfying to laugh about it on the screen!
