Nah, that wasn't your fault. Couple of points though: starting tear is really, really greedy. Since they buffed Doran's items a while back they are 95% of the time the starting item for non jungle/supports. And ulting mid-fight as Ezreal is frequently going to hurt you more than the enemy. BTW, it is much more complicated that 'freezing is bad.' Sometimes you absolutely want the wave frozen just outside of tower range, but that is something you learn with experience. Don't freeze is a decent baseline starting out.
