How do I Punch a Wall

[Athene]

Jeez, kid...I was kinda hoping that someone could tell ME how to do the exact same thing. 

Though, if I had to guess, I'd wager the writing's probably an excellent place to start.
Plus, it's nowhere near as scrape-y on the knuckles.

I wrote stuff in a journal but it just makes me feel more depressed.
It worked at first but not anymore.

I actually don't do much  journaling. I write fiction when my moods are very dark and my emotions get a bit scary.
For me, it's an effective outlet for expressing sad/depressive thoughts, and especially angry ones...without harming anyone.

You can make whatever you want happen to a character.
