I perceive anxiety and depression as two sides of the same coin. If a person had experienced one, they have experienced the other. Though we each seem to be more tuned in to one more that the other at different times. A therapist told me that my response to stress (anxiety) is to get depressed. I was surprised at first but found that to be true. Makes sense, right? Almost like Body and Mind get so tired of high-gear anxiety or panic that they eventually sink into depression. I don't know if that resonates with anyone else?
