Fiddler on the Roof

I have to figure this one out by myself;
Now that I've set myself afire
I must pleasure in my pain.

But when tears fuel fires, what is one to do?

For the careless days of youth I've left behind:
The defiant toss of my head,
The spirited spring in my step,
The sparkle in my eyes...
Have mellowed and dimmed in the shadow on my mirror.

Do I drown in you?
Or in the slumbering feelings you've kindled in me anew?
Do I need you?
Or do I need to see myself in yet another hue?
Is it me or is it you?

I have to figure this one out by myself;
Now that I've set myself afire
I must pleasure in my pain.
