Depression symptoms can vary greatly because different people experience depression in different ways. A 25-year-old man with depression may not have the same symptoms as a 70-year-old man, for instance. For some people, depression symptoms are so severe that it's obvious something isn't right. Others may feel generally miserable or unhappy without really knowing why.
