I’ve been singing the same song for 6 months.

After googling, I found this community. Hoping for some feedback. I’ve been singing the same song stuck in my head for 6 months straight with no end in sight. <br><br>It’s not a bad earworm stuck in my head, it’s actually a fully voices and produced song with a melody and harmonies and even instruments. I hear it super clear and none stop while awake. It’s the same song, even if I’m interrupted by something and focus on that voices and music continue when I’m done with whatever is I was focused on. I’ve tried to record the music and write down the lyrics. It’s a very upbeat and positive song. Not sure what to do with this, hence why I’m reaching out. Has anyone else ever had this happen to them?
