This is a 100% typical beginner mistake. I've done it. I can almost guarantee that everyone who plays NLHE has done this at least once in their early days. Don't kick yourself too hard, it was a normal mistake and part of the learning process.

Don't be so results oriented that a single hand affects the way you think of your own skill level. Make sure you follow bankroll management and play at stakes where you can lose a few buy-ins and still feel comfortable with your stack. After all, variance can 'cause a winning player to experience downswings much greater than a mere 3 buy-ins.

Put villains on a range!
