Does anyone else get a little panicky when around two people arguing?

If my mom and her boyfriend get into an argument and they start yelling, I start having little anxiety attacks and I have to leave the room. The same thing happens if my dad yells at my brother for having an attitude over nothing, or if my boyfriend's stepdad starts going off on someone over something little. Am I the only one who ends up reacting this way? My parents fought a lot when I was little, but I don't really think that's the reason why I get like this.
