How it's used
This expression vividly describes the mental exhaustion that comes from excessive rumination or trying to solve a complex problem. It implies a sense of desperation or intense pressure, suggesting that the person is literally wearing out their heart and liver through sheer mental effort. It is most commonly used when someone is stuck in a loop of worry or indecision.
Examples
Stop overthinking it, just let things take their course.
He really racked his brain over this matter.

Common phrases
racked my brain but still could not think of it
Common mistake
Do not confuse this with simply thinking about something. It specifically carries a negative connotation of being stuck, anxious, or obsessively focused on a problem that might not have an easy solution.
