Looking for a musical mentor that can also help with consistency and execution

Hey, I’m a 14 year old that is really struggling with completing songs, practicing, or making what I really want. This is a huge distress to me and am betting my whole life whether I can do it or not. I want to create a new genre called Corridos Levantados, which I will expand more on if you DM me. I can imagine whole remixes in my head of certain songs but I can’t make an original piece. I’ve already made a few shitty GarageBand projects but they’re all trash and short. Music really is my whole life and my only reason of living. I don’t do anything but just listen to music in school. I’ve tried finding real life mentors but the band teacher hates me and the guitar teacher thinks I’m weird. I come up with very unique concepts and techniques for bass and sometimes other instruments in a short amount of time, I just can’t make them come to life. Pls DM me if you can help
