struck by strong feelings of love or affection
smitten - struck
If you become enamoured with somebody or something in a sudden and dramatic way that is akin to being struck, then you can say you are ‘smitten’. The word implies an infatuation that can be overwhelming due to its intensity and the abruptness of its onset. Generally used in a positive context.
