Are these vocal nodules?
I've been belting daily for the past 3 weeks. Recently, my falsetto has started to sound broken. I struggle to have a clean onset in falsetto. It starts off as this super breathy voice before it settles into falsetto. It gets worse after clearing my throat. I can still use my chest and mixed voice, but they sometimes crack if I let up even a little on breath support. I don't know if this is vocal overuse or late-stage puberty, as I'm 16. Here's a recording. https://voca.ro/1a7LHgvDXCGO
