Jeffrey29 - don't sweat it. As everyone else has said, everyone else makes mistakes too, the important thing being to learn from it.
Once when I was still a student PPL and flying as a "passenger" in a non-radio aircraft, we set ourselves up nicely for downwind on the expected runway (based on the forecast wind) at a little uncontrolled airfield without a windsock. Just as we were about to turn base, I spotted a plume of smoke directly ahead of us. It was blowing directly towards us! A swift 180 turn put us on the opposite downwind for the reciprocal runway, and a smooth landing followed. I looked up on the rollout to see another aircraft about 150 feet above the ground and perfectly positioned to land in the opposite direction directly on top of us!!!! Suffice to say the PIC got us off the runway at a somewhat faster speed than normal and the landing plane executed a go-around followed by a circuit to land a with a 10kt tail-wind and a nice short runway...
You're not the first, and you won't be the last. Admit the mistake, learn from it, and make sure you never repeat it.
Cheers,
MD.
