I think “Rachel Getting Married” is an honest look into the lives of those who suffer from MI. I know the movie is mostly centered around drug use but she clearly has some BPD/bipolar tendencies (both mania and depression) and as someone who personally went to treatment, the reaction from her family and friends was a similar experience for me. Everyone walks in eggshells around her, even though she hasn't had an episode in months and is medicated (though struggling). It seems they've lost faith in her recovery and they treat her like she's this giant walking mass of destructiveness.

But still she soldiers on, mostly on her own. And even though every day is a battle, she appears to gain inner balance with herself. Yeah, the movie does end with happiness and love all around, but you still know that it's going to be a life long battle and she has a lot of work to do as a single human being, not a couple.

It may not be specific to what you were asking but it's definitely a real look into what a lot of us experience, especially if you've gone to treatment or even just an over night hospital stay. It's not 100% accurate but there's some definite truths in there that I could relate to.
