“曾经的好朋友如今沦为陌生人”英语英语怎么翻译

A good friend of yesterday becomes a stranger of today.

注意英语的表达，这里的yesterday 和today 并不是说过去或者现在的某一天。这里代表的是曾经和现在。这是本人的翻译。反正错是不会错了，可能还有一些大同小异的表达把。仅供楼主参考。

Once good friend degenerates into the stranger now 或A good friend of mine had become a stranger now。

A good friend of mine had become a stranger now!
