Extremely sad, lonely, and disheartening; causing a feeling of emptiness and emotional devastation.
From 'desolate' (verb) plus the present participle suffix '-ing'. This turns the verb into an adjective that describes something actively causing desolation.
When something is 'desolating' (not just 'desolate'), it suggests an active emotional impact—the desolation isn't a static state but something being actively inflicted on you.
