My concern is that because so many of the things we struggle with are internal, people watching this on their televisions are not going to see anything that they can readily identify as a handicap - just someone saying "I'm feeling overwhelmed" is not going to translate through the screen, especially coming from people who tend not to have a lot of clearly visible emotional facial responses.
I'm just worried that a lot of viewers will come away with more of that 'There's nothing wrong with these people, they're just faking and being big babies. They just need to grow a spine and stop whining' attitude.
An invisible handicap will not play to a television audience. And may make them far less sympathetic than they already aren't.
