The Fall of Doc Future by W. Dow Rieder is an online superhero novel. It was serialized between 2012 and 2013.
Those closest to Doc Future can tell something is wrong with the super-genius. Never one to share his problems with the intellectually inferior — and as far as Doc can tell, everyone is his intellectual inferior — Doc is unwilling to publicly acknowledge the toll that his prophetic nightmares are taking on him. Ridding himself of them would deny him the means to foresee world-threatening crises before they happen, so he must find some way to live with them.
As it happens, while Doc is a bright guy, self analysis is tricky. Doc does not fully understand his own problems.
