The emotional swings and such are definitely part of the healing. Your liver is cleansing thanks to the milk thistle and you're letting go of some stored emotions. The line bisecting your tongue represents stored emotions in the spinal column, for instance. Just be extra nice to yourself, take long baths, sing sad songs, go with the flow! One day soon you'll feel totally different. :)
Plus, some toxins pass through the blood brain barrier and hit the part of the brain that triggers sense memories and emotions.
