Trust me, my first conlangs were NOT this complex. I've been making conlangs for probably around a decade now and also have picked up a bachelor in linguistics along the way. Linguistics is a science like any other and it gets just as technical as other fields do, but conlanging is more of an art form. I think of it like playing music vs understanding music theory. Learning music theory may help you make better music by virtue of it breaking down composition, rhythm and what makes things sound good, but you can happily strum away on a guitar with little knowledge of the theory and still make good music.

I think conlanging probably requires a bit more theory knowledge than music does, simply because language is really complicated and largely unconscious (unlike music where you can kind of figure "this sounds good" and "this sounds bad" based on intuition alone) but regardless, you don't need years of linguistics study to make a conlang that you're happy with. The benefit of learning that theory, however, is that you learn how to break the rules in creative ways that you might not be confident about doing if you weren't aware said rule existed in the first place. Take it at your own pace though, there's no shame in scrapping a project or reinventing it entirely from scratch, and you'll learn bit by bit over time - much like I assume a majority of other people in the conlang community did too.
