Firstly as your blood work are fine so in my opinion you shouldn't worry at all.
And relax yourself.
Most probably you are suffering from IBS and stress and anxiety are contributing factors.
And Leaky gut syndrome is a proposed condition of an altered or damaged bowel lining and is not an established diagnosis,it is under clinical research.
This is a chronic condition of unknown cause in which the permeability of gut do increases and there are many factors which are responsible for that like chronic alcoholism, drug induced,insufficient digestive enzymes, diet high in carbohydrates, liver disorders and many others.
It is seen that the tendency of food allergy and auto-immune disorders do increases with leaky gut syndrome.
This can make the anxiety and depression more worse due to imbalance of food digestion and absorption mechanisms.
It is associated with many diseases like celiac, arthritis, lupus, thyroid disorders and others as well.
Otherwise the food you should avoid high in carbohydrates and in fat.
You can take food rich in protein and low in carbohydrate.
Alcohol and carbonated drinks should also be avoided.
I hope this helps.
