Here's the deal; I'm superstitious. Actually I'm not even sure that 'superstitious' would describe what I am exactly. We may have to come up with a whole new word for what I am, because I am not traditionally superstitious; I have my own issues - some of which may fall under the category of "crazy."
Being superstitious in itself is not the problem; it's the craziness close to OCD that sometimes comes along with it. For instance, during an exam if the first day I followed a particular schedule and say the paper went well, I would follow the exact same schedule - waking up, brushing my teeth and taking a shower, getting dressed, taking the train, etc. at exactly the same time as the previous day and not try to alter that schedule as far as possible. Following a particular schedule, again, is no issue at all, but the pressure of keeping up with it and then worrying when something goes wrong is too much to handle.
