。
She bounced back from the shock.
Literal
She [topic-は] shock [from-から] recovered.
立ち直る ('recover, get back on one's feet') is built from 立ち ('standing,' the masu-stem of 立つ) + 直る ('be repaired, become right again') — literally 'standing-recover.' The compound metaphor lines up neatly with English 'get back up.' から marks the source one is recovering from, whether emotional (shock, grief), financial (bankruptcy), or physical (illness, injury). A useful all-purpose verb for resilience and rebound, and one of the warmer words a friend might use to describe someone they're proud of.
