Best wishes on your slog through trauma swamp. Take good care of yourself. Green tea is a good choice. I take white tea when I can, it brings me calm and a sense of well-being.
Have you ever suffered from seasonal affective disorder? The lack of light and the drabness of the colours can be a drag on the mood, especially in the more northerly latitudes. Some folks I know invested in one of those special colour-balanced lamps that apparently help a lot.
