What's the difference between mental health and mental illness? Sometimes the answer is clear, but often the distinction between mental health and mental illness isn't so obvious.
Depression is a mood disorder that causes a persistent feeling of sadness and loss of interest. Also called major depressive disorder or clinical depression, it affects how you feel, think and behave and can lead to a variety of emotional and physical problems.
Experiencing occasional anxiety is a normal part of life. However, people with anxiety disorders frequently have intense, excessive and persistent worry and fear about everyday situations.
Seasonal affective disorder (SAD) is a type of depression that is related to changes in seasons. SAD begins and ends at about the same times every year and, if you're like most people with SAD, your symptoms start in the fall and continue into the winter months, sapping your energy and making you feel moody.
