Most of The Wall? In particular, One Of My Turns:

...Day after day, love turns grey
Like the skin on a dying man.
Night after night, we pretend its all right
But I have grown older and
You have grown colder and
Nothing is very much fun any more.
And I can feel one of my turns coming on.
I feel cold as a razor blade,
Tight as a tourniquet,
Dry as a funeral drum...

Then there's Goodbye Blue Sky, Comfortably Numb, Don't Leave Me Now, Goodbye Cruel World, etc. If your wrists aren't slashed by the time you're done with The Wall you're not really depressed.
