How to describe an angry voice in dialogue?
I've been looking for a word to describe this tone of voice for a long time but never came across it. Now let me just spread a pinch of context. It's a first person novel, and our protagonist is very emotionally conflicted within. Dead parents, dead friends, blames himself etc. The only thing he has left is his younger companion who he cares for like an extremely over-protective older brother. Our protagonist is responsible (involuntarily responsible) for some earthquakes (long story), and his younger companion at this point in the novel questions if he himself was responsible for it.
This is how it goes...
He didn’t say a word, as he stared motionlessly straight ahead. He was doing that thing where he overthinks.
“Stop overthinking. I’ve told you if you keep doing that you’ll get grey hairs.”
All of a sudden his eyebrows curled against each other, and his eyes widened with grief, “Please don’t tell me I caused that earthquake?” he whimpered.
Hearing this, I dropped to my knees, and grabbed his face, “Have you absolutely lost your mind?” I yelled.
OK. So the final bit of dialogue where the protagonist asks "Have you lost your mind," is actually the part I'm struggling with here. He does't actually yell. 522
His voice is more like a throaty growl, as if to convey some frustration as well. Hearing this from <PERSON> (younger companion) just turns his world upside down, because he would never allow his naive younger counterpart to step foot near the earthquake. Yeah, so instead of "I yelled," what the hell is that word. You ever watched the dark knight... where <PERSON> goes to the joker "Where is she?" in that interrogation scene. Well it's a voice like that, but obviously with a bit less aggression. A brooding voice. God, what's the damn word?!
Anyway, thanks if you take the time to read and/or answer my question, and sorry for my panicky tone. I get super worked up over minor word haha.
Oh, and one last thing. I feel like I could have simulated the "I dropped to my knees and grabbed his face," a little better. How do I describe holding <PERSON>'s face in urgency? 522
