Ecoanxiety is a constant feeling of dread about climate change. People who feel hopeless about preventing environmental disasters commonly suffer from ecoanxiety.
Most mental health experts consider ecoanxiety to be a more extreme form of a common, rational concern about our warming planet. In fact, a majority of people are worried about climate change and its environmental effects. When this normal worry becomes so overwhelming that it affects a person's sleep, relationships, or ability to work, it can be diagnosed as ecoanxiety. It's a 21st-century word, used since at least 2007 and coined from ecology and anxiety.
