I am depressed by my illness

Her cheerful voice responded just like that. Guess I was worrying over nothing..

I can't keep this up. It's an emotional roller coaster around here and all we have to do is look at the boss's face to know whether everybody is going to be happy or sad

She felt blue

Hence, loathed melancholy

He was overcome by a feeling of melancholy

My father's condition seems to improve one moment, but the next moment he sinks again

You are truly an antidote for my melancholy

This will bring you to grief

Somebody who wavers between hope and fear over superficial things should not be appointed to a management position

On the way we dropped in at the shops and bought foodstuffs. They say well prepared means no worries

Every cloud has a silver lining

And then I breathe a sigh from melancholy in being unable to do anything about it
