hi there! funnily enough I also go to school for songwriting (kinda, I'm a music production major but I'm in songwriting class with all of the songwriting majors and have been writing for a long time as well). if there was one text I'd recommend for working on your songwriting and lyric building process it'd be the exercises in the book "How to Write One Song" by Jeff Tweedy. he basically just shows you how to jumble up your current way of thinking about writing and finding new ways to put words together that you never thought you could do.
P.S. your line about wanting to creating lyrics that move people is very relatable and I understand that want very much and know you probably already are moving people and that as much as we want to be able to write like our heroes as soon as possible, our own just as powerful sound will come eventually with slow and hard work. I'm sure you know this but I thought I would say.
feel free to message me if you'd like to talk songwriting moreโhappy writing!
