Don't cry, really~! D: As I mentioned, there will be many opportunities for you to prove yourself, so don't think this is the end by any means. Honestly, muting isn't the end of the world, either. Yes, we do keep in mind a lot of the punishments that we tend to give our users for ignoring our warnings as well as breaking rules, but also keep in mind that people have the ability and they have the power to correct their behavior, and we tend to notice that kind of stuff in people.
We staff of the server are a lot more intuitive than you may think. When people have made behavioral corrections in themselves, we discuss it amongst us, and then bring up a possibility of that user being a future voice.
All of that is just to say that the road is full of infinite possibilities, and that the recent voice promotions will not be the only time we will promote voiced users. So cheer up! :3
