I read this article and just thought it was worth a forum to raise awareness.

Connecting Illness to Emotions

Dr. Christiane Northrup coined the term “toxic emotion”. In Women's Bodies, Women’s Wisdom (Bantam, 1994), she writes, “A thought held long enough and repeated often enough becomes a belief.” That belief then becomes a biology in which emotional stress causes our adrenal glands to produce corticosteroids - hormones that weaken our immune systems.

Suppressed anger is probably the most toxic emotion of all. The physiology of suppressed anger leads to poor behaviour choices and poor health. We need both mental and physical action to remedy the physiology of toxic, endogenous neurochemicals that build up in the brain when anger is suppressed.

Other poor behaviour choices that can lead to toxic emotions include addictions to food, alcohol, drugs, and psychologically stimulating substitutes such as sex, shopping, and gambling. These behaviours, says Elnora Van Winkle of New York University, remain until the toxicosis is gone.

Not only is this true medically but also spiritually. Some scripture that I have meditated on to help overcome negative thoughts and patterns before they become truth to me are the following:
 
Philippians 4:8 Finally, brothers, whatever is true, whatever is noble, whatever is right, whatever is pure, whatever is lovely, whatever is admirable--if anything is excellent or praiseworthy--think about such things.

Psalm 19:14 May the words of my mouth and the meditation of my heart be pleasing in your sight, O Lord, my Rock and my Redeemer.

2 TImothy 1:7 For God did not give us a spirit of timidity, but a spirit of power, of love and of self-discipline.

2Corinthians 10:4 (For the weapons of our warfare are not carnal, but mighty through God to the pulling down of strong holds - a strong hold is stinking thinking that holds you captive.
