Seriously, though. Kaladin's depression. So relatable. The biggest complaint I've heard about him is "He whines all the time!" And I can see that, looking back, but as I was reading, it just connected. I connected Kaladin's depression with my own bad spells, and it's so well described. I read somewhere that Sanderson based it off of his wife's depression, and I can really tell. It's written like it is. And yes, that does mean he comes off as whiny to some. I can't blame ya for that; I'm sorry to say I've disliked characters for much less.
This is just a roundabout way to agree with everybody else. He doesn't downplay mental disorders/illnesses. He doesn't make them little plot devices that can be discarded at a moment's notice. They feel real. And they are so relatable.
