Hi there, yes, sometimes a person will need an antidepressant and they will need to be on it indefinitely, even if to act as a kind of bandaid for their mind, whilst they embark on mercury removal/chelation.

It's about holding the broken brain together, while you go about detoxing it. Many mercury people are complete basket cases, some are dead from suicide, some in mental hospitals and many of us are just trying to get through life in whatever way we can, howver messed up we are.

So whether medication or natural, whatever helps you cope, will be necessary.

A person should do all those things if they help, plus eat the right things and avoid what they know is not healthy or toxic or allergic, plus begin to get the mercury out of them.

Mercury in the brain can puppet a person to such an extent, they can almost undergo a personality change and can be schitzophrenic in nature. If an antidepressant drug can hold that back, or at least act as a crutch? Then take it.

Problem is mercury toxic people tend to get more side effects than others, so there is usually little that they can tolerate. St John's Wart can help and that is a natural herb. But I do not know if it's for severe depression, probably more mild depression, but could be worth a try.
