Portrait of a Woman Suffering from Obsessive Envy; ThÃ©odore GÃ©ricault.

Jealousy is the result or fear of losing someone or something that one is attached to or possesses to another person (the transfer of a lover's affections in the typical form), while envy is the resentment caused by another person having something that one does not have, but desires for oneself.
