2012 what do you think?

So I'm watching a doentary about 2012. I don't really believe in it, but I can't help but be worried. My religion is against it yet I know that the mother Mary is only appearing one last time, and hey, shes been appearing for centuries so that can't be good. So how do you explain nostadomas' other accurate predictions? And why is this so big when others weren't? They talk about the sun aligning with the milky wag and stuff. Now I don't believe we will die on 12/21 but I think it's possible it could be the age of destruction. They talk about famine and war and chaos which seems plausible and could lead to the end of us. Idk. What do u think?
