Not Just “Shocked”: In English, you can be “numb with grief” or “numb with shock” to describe an immediate, overwhelming feeling. While
麻木 can be used in these contexts, it more strongly implies a chronic, long-term desensitization—a state of being worn down rather than a sudden state of shock. For a sudden shock, a word like
震惊 (zhènjīng - shocked) might be more appropriate.
