|I want (went)downstairs and I cried and I cried.
I held his hand and he could talk (at times) sometimes. (I was torn as I watched my father cry because he was so thirsty, but he couldn't have water.

Okay I typed a few ideas you can work with. This has a wonderful theme and I feel so deeply for the loss. So you have a great concept. You do need to edit, you have grammer errors which I pointed out a few, and you are jumping from past to present tence. Now at the end that is okay to be in the present because yo are going off of what is now happening, but the past should remain within that writting.
This is a great story. With a little clean up and structure, you will have a great story.
I told him I loved him, and he barely audibly told me the same. We went home.
