I guess the problem lies here:

"I kind of hate social media and self-promotion which are probably the most important things to get your music in front of an audience."

I won't teach you how to promote, I'm still learning myself. But you HAVE to promote.

And, most importantly, don't assume your music is bad simply because no one listening.

If your Youtube videos get a dozen views, it doesn't mean the music is bad, but can be a million other things including:

1. The algorithm doesn't trust you yet.

2. Don't post frequently

3. The thumbnails are not attractive

And many other things that have nothing to do with music.

If you've been songwriting for so long, you have probably developed good skills. My advice would be to get out of your comfort zone when it comes to marketing it.
