My Identity; Author Unknown

I lost my identity
Somewhere, someplace, sometime.
I can't seem to remember when
I do know, that once I was carefree
And now, today, I find I am confused
Sometimes I appear angry and know not why
The joys of life that I once loved
Now seem to have faded from me
Please help me find out who I am
If you see this happy-go-lucky person
Who loves to sing and enjoys life
Walking down a street
Stop her and take her by the hand
I think maybe she belongs to me
