不是故作沉默只是无力诉说
[bù shì gù zuò chén mò zhĭ shì wú lì sù shuō]
'Not Deliberately Silent, Just Powerless to Express' reflects frustration at inability or difficulty expressing oneself despite wanting to. Sometimes silence isn't intentional; people feel unable to articulate deep-seated emotions due to linguistic incapacity or fear of rejection/judgment from listeners.
