missing flash drive

OK. It is gone. I either lost it on the bus and someone has found it and kept it or I lost it at work and someone found it and kept it or I lost it on the street and anyway, it is gone. And I am freaking out a little. Sure, my stories were on there and yes, they're all hard drive saved. But also a few cover letters, my address, my telephone number, all kinds of stuff. I mean, if it's gone, ok, it's gone. I just am worried about my information being out there. Also, some of the query letters and synopsises (synopsisi?) I've written were not on my hard drive, so they are just gone. It's driving me kind of crazy.
