Last night I yelled at my wife, and I dont know what to do, Please see situation below?

This is what happened. My wife and i were watching the Chiefs game. The last moments were epic, the failed field goal that won the game was awesome. My wife was rolling on the floor doing what looked like the worm doing excessive celebration. She very nearly knocked the table that held her laptop over. I voiced my concern, i said "Wife's name! Stop you're going to break your laptop!" Twice but she failed to pay attention. On the Third time i Shouted it (the yelling). That got her attention and got her to stop. It was the first time i ever raised my voice at my wife in our marriage of 12 years. First time. She was not angry at me. She understood (small thing about the laptop, it was an early Christmas gift and cost me 2500 dollars), and was not mad at me. But i can't shake the feeling like i feel like a piece of shit. that i some how abused her in that situation. The reason for these feelings, Every parent i have ever had (mother and father) screamed at me when i did or didn't do something they wanted. They were also physically abusive. I am terrified of becoming them. I am so damn angry at my self.

What do i do?

For the record, because I failed to add this, she was upset at first until she saw the nearly tipped over table.
