Orphan in my Balcony

This beautiful flower was left at my doorstep by nature. My botanical knowledge being zero please help me name/identity this yellow apparition.

On rifling through the internet I feel it is a sort of marigold. A wild Calenula?

Scream of Loneliness

Small scream (Photo credit: Wikipedia)

You are alone

I know you are alone

What if you were born an orphan?

Alone?

Still you would have sought

Some friends

Made some friends

A husband

A wife

A child anew

Now, but you are not an orphan

Nor friendless

Please learn to be not alone

The World is your friend

If

You make it!

You are not alone.
