Dr Christopher taught that there are no incurable diseases - only incurable people because they won't do what they need to do to fix the problem. I firmly believe this, so, no, I don't believe you are stuck. I believe the body can correct any imbalance if we give it the correct tools to work with.
You mention that you eat alot of fruit and some veggies, but you don't mention greens or fats. It is essential to keep all of these in balance for the body to function properly.
In "Your Bodies Many Cries for Water" by Dr. Batmanghelidj, he says, "Depression and some mental disorders are the consequence of brain tryptophan imbalance. Prozac used in some mental disorders, particularly in depression, is a drug that stops the enzymes that break down serotonin, a byproduct of tryptophan. When more serotonin is present, all nerves funtion normally. However, Prozac cannot replace the indispensable role of tryptophan itself. One has to work at replenishing body reserves of tryptophan through a balanced diet and regular water intake.
My research has shown there is a direct relationship between water intake - hemodilution - and efficiency of function in the transport system for the passage of tryptophan into the brain. Water shortage and proportionate histamine release bring about an increase in the rate of tryptophan breakdown in the liver. it seems that adequate water intake arrests the increased and inefficient metabolism of tryptophan in the body. Chronic dehydration causes its loss from the pool of different amino acids held in the body. Tryptophan cannot be manufactured in the body; it must be imported through food intake. It is one of the essential amino acids. Thus, hydration of the body, exercise and the intake of right foods help replenish brain tryptophan reserves."
