Another one that gives an AWFUL depiction of bipolar disorder is "Smiley". It's chalk full of crappy internet culture cliches as well, for extra added annoyance. The side plot of main character is that she's a "recovering bipolar" i guess, since she tells the doctor she was previously treated with lithium for the disorder, but is "better now" and has "weened herself off" of the stuff. Then of course, the horror parts of the movie continue, and it's made so we're to think "maybe she's still crazy!"
