When it comes to expressing nervousness, there are numerous synonyms to choose from. Instead of simply saying 'was nervous,' one could use the words anxious, uneasy, apprehensive, tense, jittery, jumpy, or edgy. Furthermore, one could use the phrase 'on edge' or 'worried sick.' The choice of words will depend on the level of nervousness being expressed and the tone desired. For example, 'anxious' may be a better fit for a situation where the nervousness is mild, and 'worried sick' may be more appropriate for a situation where the person is experiencing extreme nervousness. Ultimately, using varied words and phrases can help to convey emotions more effectively to the reader or listener.
