There are three TV shows (that I know of) dealing with mental illness: United States of Tara deals with multiple personality disorder and Black Box and Homeland both deal with bipolar disorder. I've watched all three.
Black Box is a new series. I watched the first three episodes. But I've since stopped watching. I thought the show did a good job of showing what mania looks like: the noncompliance with taking medicine, the rush, the energy, the creativity, the intelligence.
And Homeland stars Claire Danes. This show is fantastic! Danes works as a CIA analyst who is great at her job but doesn't always know how to manage her disorder.
You should check out the shows!
I am glad that the media has sought to thoughtfully display what people living with mental illnesses lives look like. We are all not mass murderers. We can hold down full-time jobs. We might have children. We love and hurt as our non-diagnosed brethren do. We are functioning members of society. I am glad that TV shows have been becoming more and more diverse (not just in terms of race, but also other identifiers).
