I always just think of my own rage. When I get so angry there’s no turning back, there are 2 things that can come from it.
The blistering, hot, dry heat that pulls up from within me. It’s sort of like a dust tornado. Spinning, spinning, spinning with no control or end in sight. It overtakes you, until you’re filled with heat, and you just explode. Situations where this occur are usually in arguments with someone. Like, one time my dad and I got into an argument and I snapped. I just stared at him and said, in the coldest, harshest voice the worst thing I could think of, and it made me feel better, in that horribly satisfying way. It’s also silent. If I’m dry mad, I’m usually fuming internally, and one thing could make me just break open.
And then there’s the wet rage. Rage that wells up inside of you, so much so, so overwhelming that it makes someone cry. I usually experience this. Unlike dry heat, this rage doesn’t fill me as much as it consumes my chest. I feel it especially in my stomach, in my mind, in my heart. During an argument, I’m trying to choke down tears, my temples are throbbing, and my heart aches because whatever is happening then and there is just making me so fucking angry and there’s nothing I can do about it. It’s like an argument with someone you really love about something super personal. It’s like when that one person who you love the most says the truest, most hurtful thing and you just know they’re right, but it fucking hurts. This is where I usually will cry, or throw shit, or punch a wall.
Another important thing to remember is that anger is usually a sub-emotion. By that, I mean that it’s usually a sort of instinctual thing the mind does in order to protect the person. For example, I always get super angry when I accidentally get physically hurt. Or, if someone’s in my face, I’ll get mad. It’s like fight or flight. Most of the time, actually, all of the time, anger is something people use to mask the real emotion.
I think that always makes an impact when you add that in. They’re angry because that one person called them a bitch? Why, though? Like, yes, being called a bitch is upsetting, but why does it affect them to a level of rage? Is the other person right? Are they not being listened to? Dismissed?
I don’t really know, I guess when writing from a MC perspective, I always like to focus on the emotion and how that’s making them feel on the inside rather than what they do on the outside. Like, pulling their eyebrows together, gritting their teeth, face getting red. Those descriptions are really useful when describing another character (or writing in third person). I hope these helped you out!
