"you're so strong" can be really annoying to hear

Counterpoint: I have a friend, who is tends to be shy, but I thought it was just because she is like that naturally, like me. But turns out she has a narcissist for a father, a mentally unstable mother, a former friend that tried to kill her, a few stalkers, an aunt who is also trying to kill her, a dysfunctional extended family and almost no one to rely on.

She told me all of those stories, and I told her "this is insane, it's not normal, and all of your issues are not bad habits, they are ways to deal with some fucked up things". I told her she was so strong and I meant it. And she said she never knew it was not normal, and she was happy to hear it, and I think it was really important to hear.

Of course "you're so strong" can be annoying, but it can also help someone get a grip back on reality. As a general rule, if it's only annoying to some people, it can still be worth doing. I'll annoy 100 people if it means I can be helpful to even one person that's like my friend.
