IWTL about making music

So throughout my youth I was classically trained, and can play the Clarinet, Piano, and am learning the guitar and violin. I learned some stuff about music theory at the most basic level during middle/high school but its all fuzzy and I’m having issues hearing the notes/intervals, and most importantly, how to actually create music, evoke emotion, and even write lyrics (although I have some written down).

So I guess I need help finding my sound, better understanding intervals and music theory, and writing music.
