Depression and anxiety do not always co-exist, however two out of three people diagnosed with depression also have anxiety symptoms. Depression includes emotions such as hopelessness, despair and anger. Energy levels are low and the day-to-day tasks and personal relationships essential to life may seem overwhelming. Anxiety symptoms often include a constant nagging worry or fear and a feeling of general nervousness. Panic attacks may restrict a person’s ability to work, maintain relationships, or even leave the house.
