There is more than one type of depression and it varies between people. While I don't have anything that gives me mental breakdowns, I have my own issues with depression that, while they do go away, also do come back a lot, which the book does make a point of. And seeing as I read this book during my depressed scene aka now, I can confirm that a lot of it is relatable. (There's a thing called SAD (Seasonal Associative Disorder) which I have noticed that I am heavily affected by, so it does go away when winter ends, and then comes back. Every year. Same damn time. And I'm pretty sure I was depressed as a kid and didn't realize, cuz what kid knows they're storming depressed. Depressed was my normal.)
Kaladin in this book was great. Still think his strongest appearance is WoR, but this book continued his long and harrowing journey, giving him some respite before forcing him through, and boy, the more I think about it, the more connections I can make to my own life. He likes fighting, he loves it, Vasher outright says it. However, it takes a toll on him, tires him, and he needs to take a break doing something else he somewhat loves. This is very similar to me during my depressive episodes, where I'm doing something i love (writing), but it tires me and takes a toll on my mental health and I need to take a break and recover by doing something else I love (Literally anything else. Read, youtube, movies, shows, anything, just stay away from the stress inducer.) His struggle with his parents does not perfectly mirror my own, but to some extent, his parents are dismissive of his condition. My parents, while unaware of how bad it is as I refuse to tell them, are fairly dismissive to it, as they refuse to understand the why or that even their child can go through depression because 'that's for crazy people, you're not crazy' (Despite my sister admitting she goes to therapy, provided by her job, and taking anti-depressant pills, so both their kids are depressed. Wonder why.) Adolin pesters him and makes sure he isn't alone, as he knows that he needs the company to improve his mood. While I have no friend to do that because of stupid quarantine, I do have a friend who invites me on walks and I force myself to go with him even if I'm too sleepy/tired/angry/depressed to. Having talks with him does lift the burden, and being able to talk about your problems makes it so much better. (Also, while Sanderson doesn't show it much, You can be depressed and still smile and laugh. He has Syl make Kaladin smile a few times, but rarely laugh, which does happen with people you are genuinely happy to be with, it is not just acting/faking as he implies. It's harder, and it's more fleeting, but it does happen.) So, Kaladin's depression was the most relatable and dare I say realistic I have seen/experienced, at least compared to my own experiences. While not at the sheer level, I too get moments of just not being able to do anything. And ironically, that made me quite happy while reading, because boy, if there's something that can put a smile on my face, it's good writing. Now if only I can find my own Syl in the form of a boy/girlfriend/any significant other, that would be great.
