Text and Voiceover Ideas

"Do I lie to myself to be happy?"

"I have to believe in a world outside my own mind."

"I have to believe that my actions still have meaning, even if I can’t remember them."

"I have to believe that when my eyes are closed the world is still here."
- I have expanded this with my own thoughts: 
"I have to believe that when my eyes are closed the world is still here. I have to believe she is still living, breathing, laughing, smiling. Even if I forget her, to know she exists keeps my mind at rest, at least for now."

"How am I supposed to feel if I can’t feel time?"

- Taken from the film 'Memento'

My idea for the protagonist's dialogue/voiceover for trailer:

I have to believe that when my eyes are closed the world is still here. I have to believe she is still living, breathing, laughing, smiling. 

If I don’t, all hope is lost.

My mind plays tricks, erases our memories,

I forget but she doesn’t; she knows who I was. I wish I could remember through her eyes, Who am I? Where have I been?

All I know Is that it left a void, more intense than a knife sinking into my stomach, I should know. Wounds can heal, but my mind will not repair the damage, I can search hard but my mind will forever be incomplete.

Knowing she exists is enough, it has to be.
