Writing lyrics for a song I can’t play

Hi all,
I have a few songs for which I’ve written lyrics from beginning to end. The problem is that the style and genre for my songs are beyond my limits. For instance, most of them are written in a metalcore/post hardcore style. But I’m not a metalcore band. I have my guitar, a mic, and GarageBand on my phone. I have a vision in my head of how the song should be structured. But I don’t know how to put it into sound. I’ve tried reaching out to other musicians for collaboration with almost no feedback. What should I do about this? Do I just keep the lyrics as something never to be completed?
