Depression could be more accurately described as un-repaired emotional short-circuiting. It devastates health and relationships and often has a higher negative impact on our body than the toxins and poisons we expose ourselves to in our daily lives.
But why are so many people feeling so low, even though antidepressants are so widely available? 230 million prescriptions for antidepressants are filled in the United States every year. 
Research from the Northwestern University Feinberg School of Medicine found that:
* "Chronic stress does not cause the same molecular changes that depression does, but most antidepressants are based on the hypothesis that stress causes depression. The hypothesis appears to be incorrect, which means the drugs are virtually worthless."
* "An imbalance in neurotransmitters in your brain may not trigger depressive symptoms as has long been thought. Instead, the biochemical events that lead to depression appear to start in the development and functioning of neurons. This means antidepressants focus on the effect of depression, and completely miss the cause … yet another reason why they are so ineffective for most people." 
According to the International Journal Neuropsychopharmacology, some studies found that placebo pills had a better effect then antidepressants.  Well, what can you do then?
Exercise and nutrition are directly impacting your brain and emotions. Dr. James S. Gordon found that "exercise is at least as good as antidepressants… it increases your endorphin levels, your “feel good hormones.” 
Good nutrition is vital for brain function. Enjoy a whole food diet. Avoid sugar, as it is a depressant. Supplement DHA - the essential fatty acid that makes up most of your brain. Munch on some blueberries and walnuts and include B-Vitamin rich foods such as sprouts and bee pollen. Make sure you have optimal levels of vitamin D. The best way to obtain this "sunshine vitamin" is to have some Outdoor Fun.
Addressing emotional hurt and removing underlying blockages is the most essential strategy for true healing. If our soul suffers and we are so overwhelmed that we can't process an experience - consciously or subconsciously - we shut down. Anxieties and inner restlessness are very widespread today, which are nothing but unconscious, destructive fears. The Andreas Method is very effective in ridding your body of blockages without side effects.
Free Your Soul and Feel the Joy ;-)
