Ask HN: Hrs of team meetings a week is burning me out

That's just the required stand-ups. Once a meeting goes to the 50- or 55- minute mark, I start losing focus, I need to lie down, I need to close my eyes. But I am the most junior person on the team and should listen, even though most of the conversation is over my head and not-actionable for me. Is there a polite way to get out of these meetings sometimes? Sometimes I just get a shitty night of sleep and can't deal with the meetings. I don't know. I just want to vent I guess.
