I've been so afraid to 
express these feelings...
...لقد كنتُ خائفة جداً من الإفصاحِ عن هذه المشاعر
Ich hatte Angst, dir meine
Gefühle zu offenbaren …
Temía expresarte lo que siento,
Temía expresarte lo que siento,
J’avais peur
de t’avouer mes sentiments,
Avevo paura di confessarti
i miei sentimenti...
Tinha medo de revelar meus sentimentos...
