I'm grounded

I got grounded from this "fight" I had at my school
The kid I fought said I punched him in the gut
But I punched him at the edge of his shin for roughly 3 seconds with about 8 pounds force.
Not that hard as I can normally hit.
It's self-defense though since he punched me in the face.
So I'm grounded 'cause of that and I'll try to go on when I can.
My bad but normally violence is my usual-ish (if I'm not pissed off which is 50-50 chance) answer so if someone pisses me off irl, I'd half-murder them.
I'll still try to go on but I'll mostly be afk because I'm not allowed to play games so if I get caught, I'll either get hit or grounded longer. Also I'm still sick but it gotten worse so if I'm afk or something, I'm probably not on the computer, sleeping, taking medicine, playing football, tennis or basketball outside, or doing something else with my volume off. My bad but I'll try to go on when I can but not today since I'm tired.
Love you guys (Sorry Crenia and Kiwi)

It's not a big deal. Stuff happens and this seemed to happen to you. I'm grounded for grades but im allows on but haven't been cuz i lost interest in computers/games alot. I mostly work now and finish up school
