You're obsessed. You're also procrastinating about studying for your exams. Bottom line: doing well on your tests is considerably more important than watching a show. I'm sure you realize that, but it bears repeating.
This avoidance behavior is also rather troubling as it sounds like you don't exercise or socialize - you just seem to watch stuff on TV. This is really not good for your physical or mental health.
Consider this. How many times have you watched something and it turned out to really suck? After all, not everything is compelling, wonderful television. There is a lot of junk out there, both past and present. If you are giving up study time, time with friends, or exercise time, and it's to watch something awful - and you can't seem to help yourself even when you know it sucks - then this definitely an addictive/obsessive behavior, and probably one that would need a professional's intervention.
