^ My point was that anxiety and depression aren't, necessarily
(or absolutely), signs of mental illness. One can be both depressed and experience anxiety without being mentally ill. And, for the record, Lee, wasn't the one to bring up Hans Christian Anderson, it was part of the tweets she was replying to:
As Lee says, it was intentional to show anxiety and depression, but not necessarily mental illness - at least as far as "HCA" is concerned. In other words, they were depicted "more for the story" than for an explicit connection to mental illness. So, yes, like the struggles of the LGBT community, Frozen could
absolutely be a metaphor for mental illness. But it's not necessarily, nor explicitly so, since anxiety and depression are part of many challenging moments in life and do not always denote a mental illness (or do you mean to suggest that the anxiety and depression felt by someone struggling to come "out of the closet" is a sign that they have a mental illness?). Again, the metaphor is bigger than any single issue.
