In Chapter 8 , How does Nick characterize Gatsby's state of mind before he is killed?

Nick is full of illusions about Daisy. He thinks she will be calling him. He refuses to leave even though Nick suggests that he go for his safety. Gatsby wants to stay and take care of Daisy; he is convinced that he will saver her and they will live happily ever after. Gatsby is pretty delusional to say the least.
