A bandwidth arc is the storyline of someone slowly running out of emotional and mental capacity — often documented publicly through posts, stories, or tweet threads. You watch the vibe shift in real time: first they're doing everything, then they start canceling plans, then the posts get sparse, and finally they drop a 'taking a break' note. The bandwidth arc is as recognizable as any TV character's breakdown arc, except it's your friend and it's happening on Instagram.
