Its a part of the game, sometime you will lose, you can play your best game, but there are no way to win always...
I prefer to don´t care, the first thing to do are analyze your game to find if there a mistake for your part, when more hands you play, less will care with some badbeats.
But there are some hands you will never forget, it's great, will help to play better. My advice to you are to take a time, avoid the badbeat, prefer to play only when you are not susceptible for tilt.
