Why cant i do anything?

Ok my mom is kinda strict, so about two mouths ago i asked if i could get snakebites[i'm going to be 13teen in a few mouths] and she said no! Most kids my age have lip rings, but know one has snake bites so it would be cool. So last night i asked again and she sad you have unufe holes[wtf]! So my friend said maybe she mite let me get a bar so i cooked breakfest and asked if maybe if i could kep my grades up if i could get a bar and she said shut up brat! I cant go to the mall with my friends. I cant talk to my bf past 9:30pm. And she calls me a emo cry baby.
