紧急求助！请问以下内容是否为某歌歌词或诗歌什么的？

Today I do not stand here face to you optimistic or full of hope.

I am not optimistic.

I am not hopeful.

But I am sure I am steady.

I know I am a heart man.

I hold heart in my hands.

I am a heart man.

So of this I am sure you are my partner...my lover... my very best friend.

My heart-my heart- beats for you.

And today I beg you to love me

I promise you this...

I promise to hold you and to cherish you.

I promise you to lay my heart in the palm of your hands.

I could promise to be there in sickness and in health till death do us part.

I promise you... me.
谢谢大家，我不是求译的，知道意思。现在就是想确定它是不是歌词或是谁的诗歌，若是的话速告知歌名或诗名……汗，谢谢大家了……

These are lines from the final episode of Grey's Anatomy.
是台词来的，来自 “Grey's Anatomy” 最后一集。是人物,Preston Burke,的婚礼誓愿...

Complete quote:

"Christina, I could promise to hold you, and to cherish you. I could promise to be there in sickness and in health. I could say till death do us part. But I won’t. Those vows are for optimistic couples, the ones full of hope. And I do not stand here on my wedding day, optimistic or full of hope. I am not optimistic. I am not hopeful. I am sure. I am steady. And I know. I am a heart man. I take them apart. I put them back together. I hold them in my hands. I … am a heart man. So this, I am sure, you are my partner, my lover, my very best friend. My heart beats for you. And on this day, the day of our wedding, I promise you this. I promise you to lay my heart in the palm of your hands. I promise you … me."

今天我没有乐观并且充满希望的站在你面前
我不乐观
我没有希望
但是我确信我是一个坚定的人
我知道我是一个有情有义的人
