It's called anxiety. There are many reasons for it and it isn't weird at all. It's probably because of all the Dec. 21 hype. You don't think you should be feeling anxious about it but a small part of you does and you don't know why. Probably because it's been so built up for years now that we can't help but feel slightly anxious about it, like "what if!? I should go see my family again just in case next week we're all dead!". That's just my guess.
