FTP $20+$2 SNGs: The End... for now

So I finished up my run of $20 SNGs in horrible fashion... I'm back down to a BR sufficient for the $10 SNGs, but don't want to go back down. What went wrong? I started out with a horrible string of bad beats (dominated, either on flop or after, yet still losing), and the times I did finish ITM it was 3rd, normally just due to the cards. Then I had 4-6 games where I just made horrible decisions, and you can't outrun the variance if you let it affect your decisions.

What am I going to do now? I'm going to follow Dimmy's suggestion and try a run of Heads Up SNGs, and then I'm going to get back to the $20 SNGs.
