You're managing more people than your manager managed, and you're still expected to ship code yourself. That's not a you problem. The math of the job changed. Teams got bigger, the IC work didn't go away, and nobody handed you more hours.
So you're pulled fifteen directions before lunch. Standup, a 1:1, an incident, a planning thing, three Slack threads, a PM who needs an answer. By the end of the day you've been busy the whole time and you couldn't tell anyone what actually moved.
That's the real tax. You're holding six people across twenty tickets in your head, and the second you context-switch, the picture falls out of it. You know something's lagging. You just can't point to where, or prove why.
And the stuff that's genuinely stuck doesn't come to you. People don't say they're blocked. Juniors don't want to look slow. The senior dev says "still on it" when she's been spinning since Tuesday. The worst one, where your team's waiting on another team that's sitting on a ticket, never comes up at all. So you find out late, in a status meeting, when your director asks why the release slipped and you don't have a good answer because you didn't know either.
You're not a bad manager. Nobody can hold all of it at once. The information exists, it's just scattered across systems that don't talk to each other, and looking at it means a morning of digging you don't have.
