Depression is a common form of mental illness that affects more than 15 million Americans. Depression doesn't look one way, and there are many types.

Some examples of depression include major depressive disorder, bipolar disorder, dysthymia, and seasonal affective disorder. Although there are many forms of depression, some symptoms overlap. For example, many people with depression feel a sense of worthlessness.

Depression harms people internationally. There is no discrimination based on race or gender. Often, depression is genetic, meaning you are more likely to suffer from some form of depression if someone in your family has the condition.

Some common signs of depression include feeling lethargic, sleeping too much, lack of appetite, social isolation, overeating, and poor self-image. The most serious symptoms of depression that require immediate attention are feeling suicidal or not wanting to exist. If a friend or loved one says things like "I'd rather die" or "No one would notice if I was gone," these are dangerous statements and they need help.

Depression can be very serious, even fatal, if left untreated. Fortunately, help is available. A licensed therapist can support people who are suffering from depression and help them understand that there is hope; they can go through an extraordinarily painful time. Therapists understand depression and want to help people recover.
