"You're unique" is actually a really bad thing to say. It implies that you're the only one out there who's like this, and that's the last thing you want to say to someone who's going through some difficult times. I for one would much rather know that I'm a part of a community, rather than the one and only.

like, we're all unique individuals
but we're the same uniqueness
so we're all the same in different ways
