Hello Tuo,

If there is no progress i recommed that you try a chelating agent like DMSA. But it is important to follow the rules and take it every 4 hours day and night like recommended in the cutler protocol. You can educate yourself about chelation here:

There is a lot of DMSA produced in China but i heard it is often contaminated with mercury! You need to find a good quality brand or maybe you can order from overseas... Does your country allow import of nutritional supplements?

I didn't know that they use amalgam in china... interesting... Are there many people with depression/anxiety problems in your country?

Good Luck...
