“I am the most miserable man living. If what I feel were equally distributed to the whole human family, there would not be a cheerful face on earth. Whether I shall ever be better I cannot tell; I awfully forbode I shall not. To remain as I am is impossible. I must die or be better.” – Abraham Lincoln
Depression falls into two major categories; unipolar depression and bipolar disorder (previously known as “manic depression.”) The first is characterized by a persistent low mood, and the second is characterized by extremes in both low and high moods.
Major Depression Symptoms
If five or more of the following symptoms have been present in either you or someone you know for more than two weeks*, please talk to your doctor about the possibility of depression being present. Keep in mind that these symptoms could indicate a medical condition other than depression.
- Feelings of sadness and/or irritability
- Loss of interest or pleasure in activities normally enjoyed
- Changes in weight or appetite
- Changes in sleeping pattern
- Feelings of guilt, hopelessness, or worthlessness
- Inability to concentrate, remember things, or make decisions
- Constant fatigue or loss of energy
- Observable restlessness or decreased activity
- Recurrent thoughts of suicide or death
In addition, look for at least three of the following symptoms, which could indicate the manic phase of manic-depression:
- Inflated ego, envisioning of grand schemes
- Increased energy and decreased need for sleep
- Inappropriate excitement or irritability
- Increased talking and/or moving
- Sexual promiscuity
- Disconnected and racing thoughts
- Impulsive behavior and poor judgment
