Thirty-six percent of Americans — including 61% of young adults and 51% of mothers with young children — say they experience “serious loneliness.” Nearly everyone has felt that ache at some point: the quiet sense of isolation, of being unseen or disconnected, even when surrounded by people.

Psychiatrist Dr. Edward Hallowell join...

Everyone seems more stressed than ever — and oddly, some people even wear it like a badge of honor. But chronic stress isn’t something to brag about. It quietly alters the way you think. It amplifies worry, exaggerates threats, narrows your options, and makes worst-case scenarios feel not just possible, but probable. Over time, stress doesn’t just affect your mood — it reshapes your perception, your judgment, and the decisions you make. And because the shift happens gradually, you often don’t re...
