Tried to sync notes to computer -- where did they go?!

Hi! I'm in desperate need of help. I just got a new BlackBerry but I wanted to get the notes out of my old Curve 8520. I downloaded BlackBerry Desktop to my MacBook Pro (which is running on OS X 10.7.5) and hooked my BlackBerry to my laptop, then went into Notes on the side and clicked on sync notes (Sync Account: Apple Mail Notes). Now my notes are not longer on my BB, and I can't find them anywhere on my computer -- they're not in my Mail's notes! Does anyone know where they could possibly be or how I could find them on my computer? I really need them! I don't have Outlook or anything else on my computer, and at the time that I synced, I wasn't using Apple Mail at all and didn't have it set up. Please tell me they haven't just vanished. :/
