For me right now, it's My Mad Fat Diary. It just has me so addicted. I've literally watched the series three times in the past two days eeeeek! It's about a girl who landed herself in a mental ward for trying to kill herself and everything she faces after getting out. It's really emotional yet hilarious at the same time and it's just so REALISTIC. Oh and there's also the guy in my avi!
Oh, and there's also Reign but I'm too tired to go into depth.
