What is love? Lost? Found?

There once was a light but I believe its gone out
I just can't be sure, but I see it no more
I wish I had help, maybe a guide
To help me find that light inside
It once was so bright, to be seen for miles
Once it was seen it brought on such smiles
There is only darkness now, for a while
I await the day when that light returns
To be complete and whole is so worth while
So take my hand, walk with me a while
I think you might be my light, my life, my smile
