lugubrious - sad
To be ‘lugubrious’ is to be mournful, brooding, and morose, especially in a way that seems overly excessive or demonstrative. This word implies that rather than being stoic about your situation, you instead want everybody to see how upset or miserable you are. For that reason, ‘lugubriousness’ does not always elicit a great deal of sympathy.
