Waking Buddha
While I was never diagnosed by a doctor I've sometimes thought that I have some mild form of tourette syndrome because of some info I looked up about it a few years ago.
When I was around ten years old I began to twitch my nose. I scrunch it up and this has caused a slight crease on my nose like a folded and then unfolded piece of paper. Sometimes after 'twitching' my nose I then feel the need to try to 'stretch' it out by using different muscles of my face to make it feel 'normal' again.
I almost can't help but to twitch my nose. With some effort I can resist the urge. When somebody draws attention to it I feel a stronger urge to do it. I've done it for 9 years now but It's not as frequent as it was through middle school. Most of the time I don't know that I do it. It just happens.
Yeah, that sounds like it. Mine's pretty mild as well and has only gotten milder over time, especially with said coping method.
I haven't been diagnosed with it either since it was never obstructive to my daily life enough to warrant a visit with a psychologist, but it's not hard to see what it is.
EDIT: Lulz, Jen gives head.
