A new survey out says 45% – nearly half – of all American adults have experienced sadness or depression around the winter holidays. Two in five adults also say they’ve seen close relatives suffering from sadness and depression especially in December. However, Dr. Christina Davis of Indianapolis-based Christian Theological Seminary says that doesn’t have to be the case. Dr. Davis says nearly everyone gets depressed from time to time, but she says prolonged depression – upwards of four weeks – warrants attention. Symptoms generally include: low energy, sadness, loss of appetite, sleeping too much and feelings of worthlessness. For those with clinical, prolonged depression, she says it’s important for people to seek out counseling which is very effective.
