慌張 的英文怎麼說?

[1] be flustered; get flustered[2] in disarray
  in disorder[3] scramble[4] in a hurry[5] agitated; nervous

be flustered = get flustered = 慌張或慌亂，也就是腦子很亂，不知道該說什麼好，例如:

When it comes to arguing with my wife, I get all flustered.

意思就是「我跟太太吵架時，就會很慌張」。

Strike the enemy when he is in disorder = 趁敵人手忙腳亂時攻擊他

in disorder = in disarray = 手忙腳亂

手忙腳亂還有個很道地的英文，那就是 scramble。
