I have a disorder called Sensory Processing Disorder which, as the name implies, causes people to process certain sensory input incorrectly. For me, I have issues with noise. Stuff sounds louder than it does to a normal person, or certain sounds bug me more than they do for a normal person. Sometimes it's worse on random days. Occasionally I'll ask people to turn stuff down or stop talking for a few minutes because it's too loud and is starting to bug me. This sometimes causes my dad to get angry at me and start yelling because "we're at the dinner table and we're trying to have a conversation like a family" or for other reasons, which pushes me into sensory overload, causing me to start yelling back at him because at that point I usually can't control myself and I just act on impulse. My dad always keeps going and going because he doesn't get that I can't stop unless he stops yelling at me. It's stopped happening now that he's starting to understand how SPD works, but it kept happening on and off for years before now.
