Most people feel anxious or depressed different time of their life. Losing someone you love, losing a job, getting a divorce and other situations can make a person feel sad, scared, lonely, nervous, or anxious. These are normal feelings as a reaction to the stressors of life.
If a person is having these feelings daily for no apparent reason, and it is interfering with normal daily functioning, it may be anxiety, depression, or both.
Depression and anxiety disorders are different, but similar in the symptoms of nervousness, sleep disruptions, difficulty concentrating and irritability. Each disorder has it’s own cause and its own emotional and behavioural symptoms.
