Anxiety is the simple answer, solely because I know it pretty well. People in my day to day life tend to think of me as a mellow guy; a girl at work has a photo of me with the definition of 'nonchalant' pinned next to it. Nope. I'm on seroxat after having anxiety attacks during my third year of university. An example: the last thing I wrote was an interpretation of Telemachus as a worry-ridden man who watches his slaves talk to each other to calm his busy mind. Every day he walks across his grounds and becomes trapped in a bubble of liquid that seeps out through cracks in his skull. He drowns. It's a not-so-subtle metaphor for what the attacks felt like. It's very strange typing this out, as I don't normally talk about it except in very abstract terms. Have you ever tried writing? I ask because the maps seem like a creative outlet.
