If you are experiencing symptoms of depression, you are certainly not alone. According to the National Institute on Mental Health, 17.3 million adults in the US have experienced at least one major depressive episode and the majority of them sought care from a mental health professional at some point. Depression is a common response to challenging life events such as grief, a breakup or divorce, unemployment, or after receiving a diagnosis of another severe medical condition such as cancer, stroke, HIV, or diabetes. You may also be experiencing depression that seems to arise for no identifiable reason as a result of a depressive disorder.
