Do not, I repeat, DO NOT look up "Brain Worms" on Google images. I don't think I'm going to be able to eat for a week. In fact, I may need to poke my eyes out with a fork!
So, since I just found those lovely images, maybe I need to explain a little!! By "brain worms", I mean the thoughts that will NOT leave you alone in your head. You know, those little things that start off small, but then decide that you need to dedicate your entire day/week/month/life to. Things like bills, ex husbands, assholes in general, things you should have done different, etc, etc. I sure as hell did not mean those monstrosities on image search!!
