你们眼中的乐观 是假的 用英语怎么说

霸道版:What you see as optimism is just a piece of shit!
温和版：THe optimism in your eyes is nothing but fake.
问题补充：想表达自己的忧郁?用一首经典老歌里的台词吧:I feel I'm getting old before my time.
你要的翻译：My reflection in the mirror still grows pale.How pathetic!
Why on earth would I fall in love with you?
