无声折磨
[wú shēng zhé mó]
The term '无声折磨' directly translates as 'silent torment.' The meaning of this expression includes the feeling when one is suffering from something intangible or invisible - maybe it’s mental pain or internal struggle. There is no outward manifestation but inside, the individual experiences relentless, quiet agony, often caused by emotional distress or difficult-to-articulate troubles.
