Just a quick post to help raise awareness of the best television series I know of dealing with bipolar (amongst other topics) - Please Like Me. Note that series one deals mostly with the principle character's coming out story, with some mention of his mother's mental health woes. Series two (2014) deals with mental illness, especially bipolar, with more depth - it is hilarious, insightful and touching. I highly recommend.
While on the topic, there are a couple of Doctor Who episodes that also deal with mental illness in a sympathetic light. First, Vincent and the Doctor (2010) and, second, In the Forest of the Night (2014). Stephen Fry's much more serious documentary, The Secret Life of the Manic Depressive, is also well worth a watch.
