One of the few times that I feel free of anxiety is when I find myself locked into a somewhat spiritual plane, or in deep meditation. Since I am not particularly religious, I do not see this as the presence of God, per se, but more as a balance of my positive spirit against the force of my anxiety. I have to admit that I do not exactly know what this means, except to say that it is always a relief to have something overwhelm my unease. It's like taking aspirin for a headache.
Ironically, I dive headlong into things that scare me. And often, when other people are claiming fear, like on a high ropes course or something, I have readily taken the first slot so that I can confront my fear directly, get it out of the way and move on.
This general angst is different. I wake up with it. I find it in the most mundane of situations, and when there is NO situation at all. It is just a presence--unconfrontable because it has no form, no substance--it just is. Another one of those f-ing mysteries, in this case probably of biology, that I may never solve.
But what is important here is not solving the mystery of why I experience anxiety, but just knowing that it is in me. It is the recognition of "what is" triumphing over the resistance to reality. That is never a bad thing.
