Note: Cf. the synonyms to be anxious, to worry, to trouble, to bother. The range of meaning of worry is wide: it can denote emotional states of different intensity whereas its synonyms are narrower in meaning. In the sentence "His long absence worried his mother very much" worry expresses a strong feeling of anxiety. It is also possible to say: "It made her very anxious." The intensity of feeling is slightly weaker here; trouble denotes a still weaker emotion; bother describes rather a state of irritation and dissatisfaction than of anxiety. Sometimes either of the synonyms can be used in one and the same sentence. The difference lies in the intensity of the emotion expressed by each verb, е.g. Don't let that bother you (= don't think about it: it is unimportant). Don't let that trouble you (nearly the same, but also: Don't get nervous about it). Don't be anxious about it. (The feeling of fear and anxiety is stronger here than in the previous example.) Don't let that worry you (= don't let that spoil your mood; don't fear that smth. bad will happen).
