ouch, bad economy hurts

I was updating some of my spreadsheets. I dared to venture a look at my rollover IRA. Ouch. Double ouch. Infinity ouch. It is worth half what it was on July 1st of this year. That is so not cool. Seriously. Granted, the bulk of that money is in a natural resources fund. And it was doing awesome as the gas prices were rising. And now that they are falling? Well, not so much. It's painful to see. I know I have like 35 years before retirement, but still. It is hard to see half of it just gone.
