Dude, do not set back from what want in life simply because of a gifted-hidden-ability you haven't discover yet. Put yourself out there, and never forget that all things you want in life, is at the other side of fear. So, keep practicing, one call after an another, step by step, and get some small wins like that, by doing what most people in your situation wouldn't do. And in my opinion, you should not believe that the condition you are in, especially at your young age, is gonna stay the same. It will not, if you work it. You are not a stutterer, you are a human being, born out of perfection, who went on a pathway developing some stuttering in your communications, that could well be a gift. Which is completely different, and it can be changed quicker than you think. Give me a tchat, i would be happy to talk! Cheers, Anthony.
