SNGs going bad

I played like 20 SNGs or so this afternoon. Four times i busted with QQ when i ran into AA or KK on low flops. I also did the same thing with JJ twice. One QQ died on jack high flop when i got checkraised all in by A8o and he rivered A. Good play, sir. I took some horrid beats in like 8 others, and some others just never had good hands to double up with.
