You had a huge exposure and still have a big body burden. Hang in there, do more safe detox such as IonCleanse epsum salt footbath with ionizer,
sauna (sit in car with windows up, take water, niacin, vit C, multimin afterward)
Porphyrazyme supplements or NCD or NDF or Pectasol CF, etc.
See additional things that help at treatment section of http://www.flcv.com/depress.html

You likely have hormone imbalances related to the exposure, which are signif. factors in depression.
get hormone levels checked and follow suggestions depending on results
DHEA, cortisol, thyroid(see home test or consider other tests), testosterone most likely. Do you get chilled easily?
Curcumin, green tea or GT extract or black tea(theaflavin) extract supplements usually help.
