Makes sense. Don't beat yourself up too much, getting started is hard for two reasons:

1) You're learning to play correctly, but everyone makes mistakes, newbs more so.
2) Even playing correctly, bad players will still draw out, especially at lower limits when they aren't smart enough to fold. Just keep making good plays, they won't beat the odds long term. I think the math on the first hand after the turn is you're about a 20 to 1 favorite to win this pot, that's the kind of spot you want to be in!
