  Suggests one's peace of mind has been shaken by something unsettling or eerie; more formal and often stronger than worried; disturbed can also mean mentally ill, a sense not compared here.

• worried

  The most common and neutral choice, describing ongoing anxious concern about a possible problem or future outcome; milder than upset or disturbed, and natural in everyday speech.

  是最常见、最中性的说法，表示对可能出现的问题或未来结果持续感到焦虑；语气比upset或disturbed都要温和，日常口语中很自然。

  She was worried about her exam results all week.

  她整整一周都在为自己的考试成绩担心。

• upset

  Focuses on hurt feelings or disappointment after something unpleasant has already happened, rather than anxiety about the future; upset can also describe a stomach ache, a sense not compared here.

  他因为最好的朋友忘记了他的生日而感到难过。

  Implies a deeper, more serious or lingering unease, often about something puzzling or weighing on the mind; more formal or literary than worried; troubled can also describe someone with ongoing personal problems, a sense not compared here.

  表示更深、更严重或持续存在的不安，往往是因为某件令人费解或压在心头的事；比worried更正式、更书面化；troubled也可以形容一个人长期存在个人问题，这个义项这里不作比较。

Disturbed, worried, upset and troubled all describe feeling uneasy or unhappy, but with different strength. Worried is the most common, meaning ongoing anxious concern. Upset means hurt after something bad happens. Troubled is stronger and more formal. Disturbed is strongest; it can mean mentally ill.

这几个词都可以形容因某事而感到担忧、不安或不快，但语气强弱和使用场合有所不同：worried最日常，upset更强调伤心和失望，troubled语气更重、更书面，disturbed则常用于描述被令人不安的事情打乱了内心的平静。这里不比较disturbed的“精神失常的”义项、upset的“肠胃不适”义项，以及troubled的“（人）长期存在问题的”义项。

Compared meaning: mentally ill or acting in a wild, foolish way (adjective).

比较义项：精神失常的／疯狂的（形容词）。

• disturbed 本词

  Describes someone with genuine psychological or emotional problems, often from trauma; more serious and clinical in tone, common in phrases like 'emotionally disturbed', never used as a casual exclamation.

  指某人真的有心理或情绪问题，往往由创伤引起；语气更严肃、偏临床，常用于「情绪失常的孩子」这类正式说法，不会用来随口感叹。

  这位辅导员在收容所里帮助那些情绪失常的青少年。

• crazy

  A broad, informal word that literally means mentally ill but is far more often used loosely for behavior that seems foolish, wild or hard to believe, without any real diagnosis implied.

  这是一个宽泛、口语化的词，字面意思是精神失常，但更常被用来随意形容看似愚蠢、疯狂或令人难以置信的行为，并不真的暗示有精神疾病。

  She must be crazy to quit her stable job without any savings.

  她没有任何积蓄就辞掉稳定的工作，一定是疯了。

• mad

  Mainly British informal usage for 'insane', most common in the hyperbolic question 'are you mad?' to call an action reckless or foolish, not to state a real mental illness.

  主要是英式英语的口语用法，表示疯狂的，最常见于夸张的问句「你疯了吗」，用来说某个行为鲁莽或愚蠢，而不是真的指患有精神疾病。

  Are you mad, running outside barefoot in the snow?

  你疯了吗，光着脚跑到雪地里去？

Disturbed, crazy and mad can all describe someone mentally ill or acting wild. Disturbed is formal, describing real psychological problems, often from trauma. Crazy and mad are informal, used loosely for foolish behavior, not a real diagnosis. Mad is mainly British; it usually means angry.

这三个词在此都表示精神失常或疯狂，但语气和使用场合不同：disturbed 语气较正式，多用于描述由创伤等原因引起的真实心理问题；crazy 和 mad 更口语化，常用来夸张地形容令人难以置信的行为，其中 mad 带有明显的英式英语色彩。这里不比较 mad 在美式英语中最常见的生气的义项，也不比较 crazy 表示狂热喜爱或极好的等口语引申义。
