Not so good—It's time for you to get yourself together.
不要说：是时候让自己振作起来了。

Each person's path of grief is unique. Maybe it isn't time for her to get herself together yet.
每个人哀悼的方式都不一样，所以也许现在并不是让她收拾感情振作起来的时候。

Better—It looks like this is a rough day for you. How about if I bring some dinner over at 6:00?
不如说：我知道你今天过得很痛苦，我晚上6点给你带点晚饭过来吧？
