Depression can make a person feel unusually sad, worthless, uninterested in activities that used to be fun, restless or even suicidal.
Depression is a serious illness that requires professional treatment, often with a combination of medication and psychological therapy.
The American Academy of Family Physicians offers these suggestions for dealing with depression:
Set a realistic schedule for yourself. While you're getting better, don't expect that you can maintain a full schedule at a regular pace.
Try not to believe the negative thoughts, like feelings of failure, that depression causes -- such thoughts should ease as depression subsides.
