Depression is an illness that is caused by a chemical imbalance in the brain that affects how it functions. The human brain is a complex system of nerve cells called neurons. These neurons act as a messaging system that controls everything in your body, both physical and mental, including your emotional state. The neurons in your brain send and receive information to the rest of your body using brain chemicals called neurotransmitters. Depression occurs when the "neurotransmission" is incorrectly delivered between brain cells. Depression cannot be overcome just by wanting it to go away. In other words, if you have depression and go without treatment, you cannot just "pull yourself together."

Everyone who suffers from depression has different symptoms. Some symptoms cause a change in thinking such as: difficulty concentrating, memory loss, pessimism, self-esteem issues, guilt, and self-criticism. Others cause a change in feelings such as: sadness for no reason, always being tired, lack of motivation, apathy, uncontrollable temper, helplessness, or no enjoyment of life. Some cause a change in behavior such as: social withdraw, appetite changes, crying, no sexual desire, complaining, or neglecting duties to your self and others. In some cases there is a change in your physical well-being such as: negative physical emotions, fatigue, sleeplessness, restlessness, or even aches and pains.

There are many medications on the market today that can improve weak neurotransmitter signals, or improve the ability of neurons to process these signals. There are many different types of depression such as: Bipolar, Dysthymia, Unspecified, and, Adjustment Disorder. If you think you many suffer from depression, please get yourself diagnosed by a licensed professional before taking any medication.
