Is this variance?

Hi
I don't post here much but I've been lurking for quite some time. Just to give you a little backround information, I have been playing the SNGs at Party for a couple of years now. I started out at the 10+1 and gradually worked my way up to the 50+5 games. I played just under 5000 50+5 before I cashed out all of my profits and stopped playing for about a month, at which point I redeposited a few hundred dollars. I once again worked that back up and was playing the 20+2s with an $1800 bankroll. It was just about a month ago that I hit a brick wall. I now have only about $500 left in my bankroll. That equates to a 60 buy-in drop over the course of just under 500 tournaments. I have had numerous bad runs before, but nothing like this. I am beginning to think that this is no longer variance, but that there is something that is seriously wrong with my game. I hope this doesnt come off as some sort of rant, but I'm basically wondering if this downswing is approaching something of statistical significance. Is it not possible for a winning player playing well to run this bad.If so, then I need to completely reevaluate my game. Thanks for any input.
