Armageddon outta here!

Ello all,
The other day I thought of an awesome idea for a script. Initially I was totally psyched and the thoughts were swirling. But then, when I thought about completing it practically I hit, what I hear is called, a snag.
And that snag is the same snag that snagged me whenever I started trying to write the graphic novel.
The snag is this,
I'm convinced we're all going to die, or something very close to it, in around 3, maybe 4 years time.
I don't know how or what or where or when, but I'm convinced it'll happen.
When that huge tsunami struck a few years ago, everyone was all boohoo and concerts and funds for about 6 months and then we all moved on.
Some, admittedly MORE than earlier kept at it, but for the most part where right back at square one.
And I'll admit, maybe I don't know nearly enough to be proper worried, but come on, we've been burning and cutting shit up for a good 4000 years now! I'm pretty sure the planet's going to give up soon.
I'm not usually one for believing conspiracy theories wholly, but something tells me that the 2012 hoohaa might actually have something to it. I don't know if it'll be a flood, a flash or a bang. I don't know if it'll be one of them, and I don't know if it'll be all of them, but I know some bad shit is GOING to happen. I just know it.
The problem is, that now all my plans, involve hurried success. In that I HAVE to do the graphic novel AND the movie by 2011 otherwise once 2012 happens, it'll be too late.
If I have a brilliant script about football and bloggers, will people still want to watch it after whatever hits us in 2012. Will people give a shit about India and democracy and a young comic artist when we're living in fallout shelters and eating worms?
I'm not saying we'll all die. I know we won't. It can't be that easy. But I don't know, I've just got the feeling that it'll suck for a lot of us and the REST will die.
Does anyone else share the feeling?
