Depression just throws you in the water. How deep, vast or treacherous is determined by the life you have lived and the scars that you bear. It is one of the reasons depression is so different for each of us. sure it carries all the same symptoms but it truly is a universe of its own once you fall within it. The analogy of treading water is a good one. Drowning is always there pulling at your ankles but it is the depth of the water and the losing eye sight of shore that really do you in.
