Emotion

The sound/feeling of a pounding heartbeat — from nervousness, excitement, fear, or love

The tense, worried feeling of watching something that might go wrong — anxiety from the outside looking in

Irritated, frustrated, annoyed — the prickly, agitated feeling of growing impatience or anger

A queasy, churning feeling — physical nausea or simmering anger

Smiling warmly and happily — a gentle, content smile (not laughing, just beaming)

Grinning or smirking to oneself — smugly, knowingly, or while thinking of something amusing

The soft, continuous sound of quiet sobbing — also a dull, throbbing pain

Restless, fidgety, antsy — the jittery feeling of being unable to sit still from excitement, nervousness, or anticipation

Cold, standoffish, prickly behavior; also the state of something thin and sharp sticking straight up, like spiky hair or plant shoots

Feeling cheerful, light-hearted, and giddy — buoyant with happy anticipation of something fun

Trembling with excitement or anticipation — the feeling before something fun is about to happen
