is a serious and common medical condition. I would strongly recommend that you see your doctor
at once to address this. There are many treatments that are available and are often quite successful. Talk to your doctor.
Depression, or as its known major depressive disorder, is a common condition. This is thought to be due to an abnormal level of certain chemicals in the brain -- specifically it is thought that the chemical known as serotonin is abnormal and therefore causes depression. It is known that people with generalized anxiety
disorder (GAD) and panic disorder are at higher risk and therefore it is possible that there is significant abnormalities in your brain chemistry. Depression can be diagnosed by your doctor clinically -- there are no lab tests needed. Your doctor will look for feeling of sadness, sleep changes, loss of interest, feelings of guilt, loss of energy, loss of concentration, change in appetite, as well as either suicidal or homicidal thoughts. IF YOU HAVE ANY THOUGHTS OF HURTING YOURSELF OR OTHERS YOU SHOULD GO DIRECTLY TO YOUR CLOSEST EMERGENCY ROOM.
Depression is also associated with intestinal problems (known as irritable bowel syndrome).
If you have depression, there are many good treatments. One would need to rule out bipolar disorder before treatment. Talk to your doctor.
