How then do you break a cycle? My best bet is to develop a new albeit healthier and more worthwhile cycle. One that wouldn't put you at the mercy of another individual. Something that will not take you away from the real world. Anything that will not lead you to perceive yourself as less interesting or inadequate.
Someday and maybe soon enough, I will be able to stop myself. When that happens, I will look at the faces of those people, objects and activities that entrapped me with a sense of triumph and relief. But for the meantime, I have to end these relationships and activities one by one. I will, just watch me.
