I'm trying to put my finger on what's not right about this in the first place, but "in the difficult time" just doesn't read right. I can't come up with a reason why though. Perhaps it sounds so ominous: the difficult time. Though this time of difficulty, through her challenging time...
It could be difficult only for her -- perhaps a death in the family -- or for them all -- a work related challenge. You can't tell from the sentence.
