Q: Does Alaska have a mood disorder?
I’m not a psychiatrist, so I’m not going to take a guess at that. I think Alaska is clearly struggling and in a lot of pain, though. And I think it’s particularly difficult for her because she feels alone in that pain, which is what really (in my experience, anyway) makes suffering unbearable and makes one experience real despair.
But the weird thing about depression is that it tends to further isolate you from people, thereby making it ever-harder for anyone to bridge the gap and really hear you in the way you need to be heard. So it becomes progressively more difficult to feel that you aren’t alone with your pain, which can make the despair feel permanent and unsolvable.
This is the most insidious thing about depression, I think: It makes itself more powerful by dragging you away from the world outside of yourself. So I don’t want to diagnose Alaska, but certainly she lives with terrible pain, and I think she clearly feels isolated by it, and I wanted to try to reflect that in the phenomenon in the story.
