- Increased sleep is usually associated with depression; however, reduction in sleep may occur instead. Changes in the duration and frequency of sleep are common.
- Sudden weight gain or weight loss may accompany severe depression. Depressed individuals may experience nausea that discourages them from eating. Overeating may occur as a method of dealing with negative feelings.
- Interactions with others are limited or avoided as a result of severe depression. The pleasure one experiences from being with others fades and it becomes more of a chore than something enjoyable.
- The energy level of severely depressed individuals is extremely diminished. They have little energy, even for those activities that previously brought them pleasure, and may struggle with just getting out of bed in the morning.
- Severe depression makes someone feel helpless. Negative thinking can become inescapable and may even lead to thoughts of suicide.
