What went wrong

So, why does my mother still seem quite ok? And I feel like I'M ABOUT TO FUCKING EXPLODE ANYTIME? What I know so far is that she has authority over me, my sister and also a bit of my father. Me? I HAVE AUTHORITY OVER A CLASS WHICH SHOWS MODERATE BEHAVIOR, I WILL HAVE AUTHORITY OVER SEC 2 SOON, I HAVE A FUCKING LOT MORE THINGS TO BOTHER ABOUT THAN HER. Ok, next, she gets pissed off when we do something that seems wrong to her. For me? People seem to do wrong ALL THE TIME. SERIOUS PROBLEM HERE. She has some tolerance. Me? I GOT PISSED TILL ALL THE TOLERANCE IS GONE. What am I to do?
