Why A Million Little Things revisited the topic of depression in Season 4 midseason premiere

Deadline

"Like most of our stories, this one came from the room," creator DJ Nash tells Deadline. "One of our writers who suffers from depression shared that they were struggling again. Our writers’ room is a truly amazing place that I am so proud to be a part of. The writer talked openly about how their depression returned. Another writer shared that they had just written a script with them and didn’t realize, to which the writer who was struggling said, ‘Yeah, I didn’t want you to know.” Which just speaks to exactly what Rome is going through. We can be friends with someone and trust them completely, but still not want to open up about our struggles. Our writers’ room is a lot like the group of friends we portray on the show – able to joke and support at the same time. Rome’s journey is so important for us to tell."
