Is It Still 2004?

I'm having a hard time accepting that this is 2005. I don't know why. You know how you'll goof, and put the wrong year on things whenever you date them for the first few days of the new year? Then, you'll remember, and kinda laugh at yourself, and say, "Oh, yeah, it's not that year anymore! Har har har!!!" Well... This year is almost halfway over, and I still think it's 2004! I still refer to 2003 as "last year." I still date my letters, and other important documents, as "2004." I stopped laughing at myself a long time ago... I'm worried now. In an interesting twist, I DO understand that I'm 29 years old. It's just the year thing, man! Is there some sort of therapy, or something that I can go in for on this kind of thing? I'm well aware of the fact that time seems to pass faster the older we get. Years go by very quickly. Why can't I get over this thing? Someone, please, help me!!!
