Depression and fatigue are both common in women, and the two conditions appear to fuel one another. People who are depressed are more than four times as likely to be tired, and those who are fatigued are almost three times as likely to be depressed. The stress and worry that are hallmarks of depression can keep you tossing and turning all night, and if you drag through every day you're bound to feel miserable.
What to do: "Treating the depression will give you more energy," Fryhofer says. Talk to your doctor about how you're feeling. He or she will want to know when your symptoms began, how long they have lasted, and how severe they are. Together, you can then determine the best course of treatment, which may include antidepressants, psychotherapy, or both.
