I found the following poem online and I hope the author doesn't mind me sharing!
People often balk at the term 'co-dependent' and can sometimes associate it only in addiction terms. In a wider sense co-dependent behaviour simply describes a person who satisfies their own needs through relationships that deny the self. This poem is a wonderful description of how some of us live our lives through others. On the surface this can feel right and is no doubt viewed by many as kind and selfless. And yet where we find ourselves consistently putting others before our own needs, this behaviour can leave us feeling unfulfilled, empty and alone.
Read on and see whether you can identify with this poem - I know I can.
