bear (one's) cross

To cope with a burden or challenging situation. I'm sure it's not easy to live with such a serious illness, but she bears her cross with such humor and grace. A: "I don't know how Nancy bears her cross so well." B: "Right? I would definitely struggle to raise four kids on my own." The interns aren't thrilled that I assigned them that boring data entry project, but, come on, we all have to bear our crosses at work!

Fig. to handle or cope with one's burden; to endure one's difficulties. (This is a biblical theme. It is always used figuratively except in the biblical context.) It's a very painful disease, but I'll bear my cross. I can't help you with it. You'll just have to carry your own cross.
