Shortly after leaving home, age 17.
Scene 1:
Most of the day spent lolling about in front of an uninspected gas fire in my unhygienic, government-sponsored flat, smoking heroic amounts of sensimilla*.
Scene 2:
Regaining consciousness, lying face down in the unheated hallway. Arms by my side, wondering why I was banging my face repeatedly into the roughly-carpeted floor. The more agitated I became about my preposterous behaviour, the harder I slammed my face into the floor. A couple of minutes and one very broken nose later, I properly woke up and decided it was time to stop injuring myself.
I think this might have been my first, and hopefully last, fit. I wouldn't recommend it.

*yes - I'm that old
