Everything turns out for the best. 气运自会好转. Don't fret.Things will get better. 不用焦虑, 情况会好转.
You gotta have faith. 你非得有信心不可. The worst is over. 最坏的阶段已成过去.
Take heart! 坚强点儿.
Every cloud has a silver lining. 每件事都有好的一面. There are two sides to every coin. 任何事都有正反两面.
Heck! A door slams, a window opens. 去他的! 人有一失, 必有一得.
