An intense longing or yearning for someone or something to happen in one's life. Angst by its modern definition does not necessarily carry a negative connotation, and can be a positive emotion that many people seek out in relationships or in life. Angst is also common in dramatic relationships and can be a driving force that pushes two people to be together because of the fact that being apart from each other makes their hearts yearn for each other. We call this being 'angsty'. Being angsty is the result of having an excessive amount of angst in one's life.
