metaphors

My blogging is stagnant like my recovery. I am so busy in these days that I simply don´t have time or energy to be more proactive in it. I am finishing my immunology paper and I am really excited about it. I can sink down to teh immunological microworld where things are so complicated and easy at the same time and stay there for hours without any focusing on myself. Yesterday i´ve been thinking about metaphors in immunology. We call the actions of the cells with our human-like verbs. They attack, hide and seek, protect, self sacrifice or commit suicides an so on. In fact man can interpret all these actions with chemical and physical rules. They don´t think or decide about their destiny. (Do we?) At one level metaphors might make perfect sense, but at other level might be sometimes insufficient and misleading. What is the relationship between reality and metaphor in a field where they are so interconnected that we can´t think them separately? Mistaken metaphors often lead to mistaken conclusions.
As usual I stretched this thought on anorexia. I have always problems with personification of my eating disorder. During therapy, I was often supposed to write letters to anorexia, say no to anorexia, blame anorexia... and I often fail in it. I wasn´t and I am not able to personify the illness-"her"- from myself. When writing and explaining, when learning and teaching and sometimes just during a dialogue with my friends I enjoy inventing new comparisions and metaphors. Does my unability to dissociate mental illnes and self play some role in the fact that I am doing quite well in recovery, but at some point I absolutely lock and can´t move forward?
