。
She was kind enough to help me.
Literal
She [topic-は] kindly [emphasis-も] me [object-を] helped-for-me.
手伝う (てつだう) takes the person helped with を — 私を手伝う ('help me'). The polite ました ending signals the speaker is recounting this to someone in a somewhat formal context. 手伝う specifically means to assist with a task or chore, as opposed to 助ける which implies rescuing from difficulty.
