What a disappointment! 真让人失望! What a pity! 太遗憾了! It was a waste of effort. 白费力了。 a wild-goose chase 白费劲。 All that for nothing. 前功尽弃。
You let me down. 你真让我失望。 I blew it. 我真失策。 It can't be helped. 毫无办法。 It's a waste of time. 纯属浪费时间。 Almost! 差不多了! I feel sad. 我感到悲伤。 I feel really sad. 我感到非常痛苦。 Oh, dear! 哦!天哪! Boohoo. 呜呜! My heart broke. 我的心都碎了。 My heart has been filled with grief. 我的内心充满了悲伤。 The sad story depressed me. 那悲惨的故事使我心情抑郁。
How ruthless! 真无情! No one can understand how I really feel. 没人能知道我的感受。
