What might paul laurence dunbar mean in the following lines from his poem "we wear the mask"?

We smile, but O great Christ, our cries
To thee from tortured souls arise.

This means that we pretend to be happy by smiling when in reality we are feeling very miserable inside. What facade we offer to the world is in direct contrast to what we really feel. We wear a mask to cover our inner turmoil.
I hope this helps feel free to ask more questions on :)

C,F there you go I hope it's correct
