  Depression has many disguises. The ones of absence and paralysis I have already attempted to describe. There is also the face of anger and frustration. The times when merely the sound of conversation drives your to distraction.
When you lash out with your tongue at those closest to you. Tension stretches you like an elastic band until you quiver at the slightest thing. Then there are the tearful days. The days when an affectionate touch, and advert, a news item swamps you with despair. Or for no reason at all, tears overwhelm as if they will never stop. Of times of crisis, I have written in Diet Coke and will not repeat myself here.
Not everyone will experience depression in all of these ways. Other people would describe shades of darknes I have never felt. Sometimes it will be a shadow that darkens life for a few hours, a few days, a few weeks. Sometimes it will last so long, that if there is a light at the end of the tunnel, you no longer remember its excistance. Individual. Sharing common symptoms but as unique as each human being.
