Depression The normal ups and downs of life and the feeling of sad and “the blues” from time to time might mean you may have a mood disorder. And if you have that feeling of emptiness and despair that has taken hold of your life and will not let go that could be a sign of depression. Depression makes it tough to function and enjoy life like you once did. And getting through the day can be very overwhelming. But not matter how hopelessness you feel you will get better. Understanding the signs and

chemicals such as serotonin‚ norepinephrine and dopamine (neurotransmitters that improve mood and emotion) being low in the brain (most prevalently in the limbic system and upper brainstem) during major depressive episodes. Antidepressants work by increasing the levels of these neurotransmitters in the limbic system‚ which they do by blocking various aspects of the synaptic transmission process. However‚ because some of the neurotransmitters such as norepinephrine are contained in neural pathways in
