We can all get depressed as a response to an upsetting situation happening in our lives. This can be significantly uncomfortable and disruptive to normal functioning, but if it is related to a known circumstance, it often resolves within a reasonable period of time. When depression is persistent, is not related to an apparent cause, or recurs frequently, treatment is appropriate. There are a range of depressive disorders. All of them affect mood, energy for living, and your outlook. All of them can affect energy, appetite, sleep, emotions and relationships. Diagnosis and treatment are helpful in understanding your condition, making choices that support your well-being and finding relief.
