Last year, a good friend of my friend passed away. His death affected my friend deeply to the point that my friend was determined to find evidence of the continuance of consciousness after death and becoming extremely depressed. My friend believes that life is utterly meaningless if there is no consciousness after death, to the point where he's considering suicide because once he's dead he wouldn't know he committed suicide, and those around him will eventually die and not know that he committed suicide.

Due to this, he doesn't want to accept that consciousness may just boil down to natural processes and is hoping that there is something more.
