你好，我想問問「無病呻吟」的英文翻譯：他沒事就喜歡「無病呻吟」，好像全世界就他過得最辛苦一樣。

→ He whines every other day as if he suffered the most in the whole world yet from nothing big deal.

I'd just say "He whines all the time." or "He complains all the time." The former is probably better in this situation as the word "whine" conveys the meaning that the subject complains in a self-pitying way.
