Wow, darkness is like a gem for me.  It is literally the place that makes me look up. Frankly, it is one of the only places that changes me.  It is the shreaking pain of uncertainty, the sudden feeling of a loss of control (when I realize my husband is in a platonic friendship with a female co-worker, and I can't possibly keep him all to myself) or when the tingling in my fingers makes me fear that I have m.s. and that I will lose functioning.  That darkness heals me as I enter it and look at it and surrender it.
