I had the same problem when I was younger and in school, I'd come home and just let everything out, which usually took a turn for the worst. Parents would pretend to call the police, and things would escalate further. I can't really provide any tips or tricks since I've kind of dissociated myself from this point in my life and I try not to really look back on it because then I just get angry at myself. Anyway, just wanted to drop my two cents here to let you know you're not alone.
