Cheer up! You'll get a new job.
I feel blue./I feel low./I feel really down.
I've got the blues today.
I feel down in the dumps today.
No one understands me. It's depressing.
Don't talk like that! I understand you.
It's sad. 真可悲
It makes me feel depressed.
Rainy days get me down.
Rainy days make me sad.
I feel blue on rainy days.
I don't feel like doing anything today.
Come on! Let's get moving. 好了,快点儿
I don't have any enthusiasm for life.
He looks melancholy. 他满脸忧愁
He has a melancholy look.
He looks gloomy today.
