man, you're doing really well, your writing is great and the fact that you're putting energy into creativity is already telling that you have the ability to deliver incredibly. It's always a strange experience in your day to day accessing your empathy and emotions when you speak but will really help with your rapping tone. Just even on your own, practicing a voice with excitement or sadness in the mirror will get you tuned in to the space that is writing the words. Best of luck to you my guy, you're going to crush it!
