I used to feel like that in the past, so I understand you. I would have a wildly different voice depending on the emotion that was dominant. It kinda flattened for me though, but I wonder if that's because I speak from the tippy top of my range now. Interesting.

Either way, I suppose the only real way to see what happens is to just go for it. I know that's fairly straightforward and probably not a big help, but you really won't know what it'll all come to if you don't start, y'know? I know when I started that I never thought that my deep voice could ever amount to anything remotely useful. But here I am I think.
