I'm no doctor, but I been burned out a few times. A look at your recent history might be helpful. Do you have months of long hours and stressful work, unappreciative bosses, lack of sleep, no exercise, bad diet and alcohol? Then it's burnout. If you or any close relatives have a history of depression, or you have had a traumatic experience (i.e. end of a relationship), excess drug usage etc. it might be depression.
