When I like a show/find a show, my OCD kicks in and I not only have to watch every episode as they come on, if I've missed 3 or 4 seasons I HAVE to watch every episode back to back until I'm caught up.

I also do this with looking at pictures on a website for example. If I'm looking for a hairstyle, I have to look at evvvvery page until I've looked at them all. If there are 25 pages, I have to look at all 25 or I feel it's not "complete" or balanced or something.

All of the above is when my anxiety/everything else is aggravated.
