隐忍只怪自己不够狠
[yĭn rĕn zhĭ guài zì jĭ bù gòu hĕn]
Meaning 'enduring silently is just because I wasn’t ruthless enough myself.', This implies frustration stemming from perceived weakness or lack of firm action. The sentiment here is about the inner conflict between needing to express emotions and the self-imposed suppression, criticizing personal inability to take decisive or assertive measures.
