Stay-at-home moms struggle with sadness, depression, and anger more often than employed mothers do, according to a sure-to-be-controversial new Gallup poll. While 26% of stay-at-home moms reported feeling sadness much of "yesterday," that figure was just 16% among employed moms. Some 28% of stay-at-home moms said they have been diagnosed with depression, an assertion made by just 17% of employed mothers. Meanwhile, 50% of the stay-at-home group felt stressed and 19% felt angry "yesterday," versus 48% and 14% in the employed group. The poll comes on the heels of a furor over Ann Romney's stay-at-home status, Politico points out.
