How To Find New Style? Feeling Stuck In My Sound

Hello looking for some advice from other creators! I’ve been rapping for about 5 years making memphis phonk rap for the most part but I’m kind of tired of making it, I also feel like I boxed myself into a certain sound and idk how to get out and experiment with other styles properly, I have developed my voice to that certain kind of style for those beats but when I try anything else my voice just sounds so weak and it’s super uncomfortable just something is off compared to when I rap on memphis beats it clicks in a certain way because I’ve practiced it a lot I guess, it’s more aggressive but I want to make more chill music something more vibey as it fits my personality more I’m a super laid back quiet guy irl and the Memphis stuff doesn't feel genuine to who I am.
