From The Far Side Of The Glass...anxiety

One important source is shedding light on anxiety: Google. As reported by economist Seth Stephens-Davidowitz, searches for anxiety have doubled in the past eight years. Certain terms are typed more often: ‘anxiety at night’ is skyrocketing, while ‘anxiety in the morning’ is also on the rise.

A second factor is opiate withdrawal. Stephens-Davidowitz notes that searches for that term are climbing even as prescription rates are falling, which could be accounted for by the black market and increased heroin addiction.

Interestingly, memory plays an important role in both addiction and anxiety disorder. With addiction, positive reinforcement creates an insatiable urge to revisit the experience. An addict’s aggressive nature partly depends on recalling the feeling of the experience. Soon this spirals into negative reinforcement, where a potential inability to return to that state keeps the user focused not on pleasure, but fear of withdrawal.
