Security of self is an easy thing to take for granted. The sense that despite what may happen outside of you, you know who you are and you know that it is your life you’re living. For those of us who have dealt with depression or anxiety, or experienced the trauma of a panic attack or a nervous breakdown, there’s a stronger sense of how important, and how fleeting that security can be. In a way, it’s everything you have, because it’s one of the only things that can’t be disconnected from who you are. Or I suppose, it is who you are, and that is a terrible thing to lose. An insight deftly examined by Writer/Director Sean Durkin in Martha Marcy May Marlene.
