catastropharian 

Also found as Catastrapharian.

1. Someone who overplays or otherwise overstates negative events. Catastropharians thus create a ‘mountain out of mole hill’ or worse. Such usage also includes the hypochondriac’s reaction to describing a trifling malady such as a hangnail.
2. Someone who invents catastrophes when there are none. This would be akin to Chicken Little’s ‘the sky is falling’ pronouncement upon experiencing rain.

3. Alternately, someone who literally takes a bad situation and turns it into something worse, thereby creating a catastrophe.
