The frowning2 emoji and its close friends are the go-to for expressing low-key frustration or mild despair. A string like 😕😓😩 fits a tough Monday morning text, while 😩😓😔😡 captures a slow buildup of annoyance after a long day. For more intense vibes, try 😩😓😔😖😢 in a post-argument message or 😔😩😣💔😓 when sharing a sad story. They’re subtle but speak volumes in both DMs and social feeds.
