Hey :0 I rap with a friend of mine (mostly write the lyrics lol) who's currently blowing up so I totally get it. There was a time where we had to take risks and go big. In this case, there's nothing to lose by trying. But tbh, I really do think you will do great, and I'm sure it is quite possible for someone like you to get a response. It's great that you are pursuing so young. Major respect lol. And even if you don't get a response, don't you ever let it get you down. Use it as an opportunity to grow and become even better. Just keep trying your very best, I believe in you :)
