总是哑口无言最终露出疲惫
[zŏng shì yā kŏu wú yán zuì zhōng lù chū pí bèi]
It can be expressed in English as "Always speechless in the end showing exhaustion". This implies that this person usually has nothing to say due to certain reasons at last leading only to physical or mental tiredness being revealed, maybe reflecting inner frustration and powerlessness.
