“Adding anxiety to depression is a bit like adding cocaine to alcohol. It presses fast-forward on the whole experience. If you have depression on its own your mind sinks into a swamp and loses momentum, but with anxiety in the cocktail, the swamp is still a swamp but the swamp now has whirlpools in it. The monsters that are there, in the muddy water, continually move like modified alligators at their highest speed. You are continually on guard. You are on guard to the point of collapse every single moment, while desperately trying to keep afloat, to breathe the air that the people on the bank all around you are breathing as easily as anything.”
