As far as in the last five years, where I've actually really liked my writing, it would probably be "Candy Hearts" or "Rage and Love". They're both Green Day fics. I didn't even post "CH" on Mibba. It's a four-part story and rather trite and short bullshit. It's a series of letters. And it just makes me want to gag.
"Rage & Love" was an interactive story on the GSB boards years ago. Mainly because I killed characters too much, so if they reviewed I wouldn't kill characters. It had so many near-death scenes due to this, so way too much drama and no cohesive plot. (And then I killed them anyway.
)
