Cover art for Be Brave lyrics by My Brightest Diamond

The song is aimed at her, but it's more specific than just giving herself courage. She sings about how she feels uncomfortable, like she doesn't belong where she is. Based on most of the lyrics I feel like she's singing about depression. It's hard to be hungry and happy, it's easier just to be. She's disconnecting from her emotions, like it hurts or it's a struggle just to feel anything. But she knows she has to, and she knows she has to change if she wants to live her life, so she forces herself to. Puts herself under house arrest, beats herself by being angry. Or being anything really.

Maybe donning her mask, dress, and finger bells is a metaphor for writing music? Like, performing helps her cope with the shit she goes through, like it's happening to someone else and not her. At least, that's what I get from the song.
