I keep going from no emotion at all to exploding with rage within minute intervals. My mom says I keep acting like some dumb, mindless zombie who doesn't ever show any emotion, but seriously I think I'm actually going to punch someone/thing because I'm so mad I feel like I'm going to scream. I have no clue why either. Usually I'm the calmest person in the house and I usually never get this mad over anything. I have no clue how to deal with it peacefully and non destructively. The last few times I got this upset I would do something like drop out of public school and into homeschooling or run away. Right now I just want to walk out and never look back, but instead my mom has me in my room as punishment for being a little brat. That's probably a good thing, even if I am sulking around like some PO'd lion in a tiny cage.
Anyway, what's a healthy way to release anger? I don't want to end up kicking my window in or something dumb that will make my mom kick me out.
