Over think

Over thinking. Is there really a psychological explanation behind it? I feel like as a psychologist in training I somehow have the authority to make up or create a disorder that classifies it as somewhat sane. Why do we do it though? Is there already some kind of explanation for it? Is it some kind of insecurity or expectation we're trying to live up to in terms of impressing someone that we fret over the tiniest things trying to find an explanation for absolutely everything. I know for a fact that I over think most things if there's time to actually think about what has occurred. This is part of the reason I have a tiff with romantic comedies. They make it somewhat sane to over think simple situations obviously pertaining to male and female attraction to one another. Does he/she like me? Are they the one? Which when the rest of us civilian population sees it we think "oh okay so I'm normal" without remembering the fact that movies aren't real they're scripted with people paid to say those things. People advise you to live simply and not read into things but if you don't what are you left with? Could you be missing something or by pass your own destiny? It's a serendipitous (my favorite word) situation. You're damned if you do damned if you don't. Sometimes I feel like God is up there rubbing his hands together laughing at some of our misfortune as though he planned all these complex dilemmas which part of me believes and the other part isn't sure what to think.
