begrudgery

Envious; feeling resentful or angered toward someone for a perceived advantage or success, material or otherwise.

(slang) Envy experienced toward friends.

(dialectal, Scotland) Showing the effects of much weeping; marred or swollen in the face through continued weeping.

A portmanteau of friend and envy — the specific jealousy you feel toward a friend who has something you want, whether it's a cooler job, a better relationship, more followers, or seemingly effortless success. Frienvy is the social-media era's name for a very old feeling: rooting for your friend while quietly resenting their wins. It's distinct from regular envy because the closeness makes it hit harder and feel guiltier.

Suspecting rivalry in love; troubled by worries that one might have been replaced in someone's affections; suspicious of a lover's or spouse's fidelity.
