I know it sucks when your money is in the hands of someone else, but when I used to use Cryptsy, they have never 'lost' any of my coins. Now, their trading engine is complete shit, and sometimes deposits took forever, or I couldn't place any sell orders, or like in your case, my coins 'disappeared' after cancelling a buy or sell order. However, the coins always returned, assuming when the trade engine stopped shitting the fan. The longest it took for me was 11 hours.
So just relax, have a beer or smoke. Your coins will be returned. When they are, re-evaluate your relationship with Cryptsy, and maybe move to another exchange that doesn't constantly have problems.
I like your perspective. I did go out of my way to say "missing" instead of "lost". I just was a bit more concerned than usual because I haven't heard of this specific issue. Usually its more along the lines of missing deposits or whatever.
Just like gnode I can confirm my coins have eventually shown back up as well. Catastrophe averted.
