I have, a'propos something completely unrelated, realized a particular anxiety spike I get at a certain stage of creative projects is something that's happening because of shit my father used to do. In this case it should be easier to deal with (I wasn't sure WHAT it was, now that I do I can learn to ignore it) than another thing I figured out quite recently, which will be much harder to root out, but bad stuff added when you were just building up your habits from ground up can be so messy ugh.
