Sleeping problems
Depressed patients may feel so tired that they need to take an extra break in the afternoon and have a hard time waking up in the morning, even if they went to bed early and had a nap in the afternoon. They might experience the opposite and feel anxious and irritated, which impairs their ability to catch some sleep. They might have insomnia as a part of the depressive symptoms, and this usually affects their perceived fatigue as well.
