thanks so much for the response. I used to

do doctor check a lot, but the doctor could not find any problem on my body no matter how much I complained about my healty to them.

My mum is a doctor, I used to consult with her, It does not solve the problem becasue all of my healty index are good.

my mum is allergy to chemical stuffs, but it looks like I am more complicated.

In general, I found out food has really big impact on my body/mood reaction, althought all healthy index look good.
