Mental illness really is as bad as having a shattered leg. We can't see it, but it can inflict just as much pain and is just as effective at stopping someone from moving forward. The worst part is our mind betrays us and copes with it by using logic to convince us that it's okay even though we're hurting. I'm glad she didn't listen to her logic.
That prince is a master marksman with how many of his lines have been hitting the bullseye.
