I'm new here, so don't take what I say too seriously, but, maybe this will help...
I'm angry that my dad died. I'm angry he didn't include me in his will. I'm angry my mom didn't abort me. I'm angry I have to deal with these...small minds...on a day to day basis. I'm angry I've been working since I was 15, and have nothing to show for it. I'm angry I don't have any friends, or a significant other. I'm angry bad people get nice things, and good people suffer. I'm angry when FB decides to show animal cruelty pictures on my feed. I'm angry when the birds sing when the sun comes up. I'm angry at the cold. . . .But mostly, I'm angry at myself for being unable to stop being angry.
Life sucks sometimes, it's just the way it is, but, hopefully, hearing about other people going through (or having gone through) what you'r going through, will help.
I know reading your post help'd me. It's a very wonderful thing to know that it's OK to feel that way. Honestly, it's ok. I wouldn't recommend throwing books at people, they're not gonna read it anyways
Try throwing the knowledge in that book at them, might just give someone a black "mind's" eye.
Exercise REALLY helps A LOT too. Even if it's just pushups or jumping jacks, physical exertion is a very solid and good use of that angry energy. Every time I feel the rage coming on, I clam up, and start singing Disney songs in my head until I can go hit a punching bag or the track.
Honestly though, at 13......Dude, puberty is a PITA ![Mad :x](./images/smilies/icon_mad.gif)
