There are many reasons why the mayans were probably wrong. One of these being a calender difference, can't remember the specifics but you could look it up. On a relatively unrelated subject, I saw a serious article tha claimed the mayans must have been aliens. It made me lol.
I have had phases of believing the world was going to end, but completely separate from everyone else (i.e. not when there were various news reports about it). Freaked my friend out once cause i was at a sleepover and felt like i wasnt gonna wake up. prob shouldnt have told her, but another friend felt the same. then nothin happened so you are not alone in feelings of impendin gloom
