Even if your heart is in the right place, reassurance probably won't do much to ease an anxious person's mind, according to Galanti. "Often, what people do when people are worried about something is tell them, 'Don't worry, that's not going to happen,' but the truth is, you don't really know that," she says. "You can't promise that, so it doesn't help."
What anxious people actually need, she says, is to accept that yes, there's a possibility that the thing they're worried about can happen and they have to be able to live their life anyway. So the best thing you can do if you want to help is not downplay or invalidate their worries.
