You might want to read Grady Hendrix's horror-satire The Final Girl Support Group. The novel deals with almost every one of the slashers in some form in this film but does so from the perspective of asking: "What's its really like to be the one left behind?"

The novel is both a brilliant satire and also deeply sympathetic to all of the women who are the survivors of the massacres. It actually argues all of the films that were made about them were all essentially based on true stories and any casual horror fan can fill in the blanks of what film they're referring to. There's a Texas debutante named Marilyn, a woman named Heather who deals with a delusion that her killer came to her in her dreams, a girl whose older brother killed her family while babysitting...

I actually think this is the kind of book that serves as a tonic to all slasher films because it actually deals with everything that's lurking beneath the surface of them as you listed here. And it's also hystericall fun along the way. I recommend it before it inevitably gets turns into a horror film itself with no irony involved.
