Donnie Darko Syndrome, or...
A howto guide to opening a time portal through which one can send an artifact back in time to murder the self before that self is able to get any further along with this madness. The only way is to just let it all happen. The tangent universe has already been set in motion, and with it, its own inevitable obliteration, along with all phylical traces that it ever could have existed. The only remnants left behind live in the dreams of loved ones.
When one realizes that one may be utterly incompatible with the universe into which the self was born, the Donnie Darko path may be the only viable way to exit with any integrity left, while also not harming anyone else, or otherwise upsetting the apple cart, so to speak.
