Analysis of A Song

I am as weary as a child
That weeps upon its mother's breast
For joy of comforting. But I
Have no such place to rest.

I am as weary as a bird
Blown by wild winds far out to sea
When it regains its nest. But, Oh,
There waits no nest for me.

What think you may sustain the bird
That finds no housing after flight?
And what the little child console
Who weeps alone at night?
