Am I mistaken, or is this an older chart, not one for the past few days? How are you feeling now? I wonder if you naturally have some inclination towards morbid thoughts, with Mercury (thought) square Pluto (lord of the underworld.) A hard Pluto transit can also make you feel like cocooning or metaphorically going underground. Transiting Pluto is starting to square your Mars (energy, initiative) and because it is part of a collection of planets (Saturn, Pluto) you may be feeling more depressed (Saturn.)
