We know that mental health issues—including depression—are incredibly common (about 16 million Americans, or 6.7% suffer from depression alone, according to the NIH). And recent tragedies like the passing of Kate Spade only make that all the more clear. But what we don't always know is what to say, or how to help, a friend who counts themselves as one of those 16 million. What do you say to someone who's dealing with depression? How do you offer them help without coming off like you understand what they're going through when you really don't, or without offending them? It's a significant challenge to anyone looking to be a good friend.
