Which character's depression do you relate to the most?

Bojack - Self-destructive, fetishizes his own sadness, gets opportunities to do good things and pull himself out but he sabotages himself so he can go back to the comfort of being unhappy and cynical. He has people who care about him and try to support him but he pushes them away. On paper, his life should be pretty awesome and a lot of people are jealous, but it just isn't enough to make him content.

Diane - Is trying to find a purpose in her life where she can make a difference and contribute positively to society, but every time she tries to do so, it turns out to be bullshit to fulfill someone's selfish ends.

Princess Caroline - Stuck in the same job she hates for 10+ years as she watches the clock tick and she gets older and older, missing out on the peak years of her life. Eventually she wants to get a better job, start a family and have kids, but that'll have to happen next year.. or the year after that..

Mr PB: Puts on a happy face and tries to be as positive as possible to hide his inner emptiness, but deep down he knows that life is meaningless, and this is all just killing time until the inevitable end.

I'd say probably Diane for me with a bit of Bojack.
