用法

You want to but lack the strength/ability to pull it off - 想帮忙却力不从心 (xiǎng bāngmáng què lìbùcóngxīn) willing to help but not up to it.
Key nuance: the will is there, the capacity isn't - often about age, health, or resources falling short of intentions.
Set idiom, slightly formal; predicate use, commonly after 感到/觉得.
