Is there a word for sad & angry? [closed]

I am trying to find a word or phrase that would express being sad and angry. Any suggestions?

It's unusual to see someone display anger and sadness at the same time. Without further context, I can suggest "sullen", which implies a silent and gloomy irritation.

• a sullen look, attitude, manner
• a sullen countenance
• sullen students protests

"sullen" - gloomily or resentfully silent or repressed. (implies a silent ill humor and a refusal to be sociable) MW

Perhaps resentful captures the feeling.

Feeling or expressing bitterness or indignation at having been treated unfairly.
‘he was angry and resentful of their intrusion’
