My freshman year in High school, I fabricated a story about a girl I met online to stop assholes from calling me gay. The story ended up snowballing into her cheating on me when we first met, and my ex-girlfriend thinks it's true still. Even though I told her "Everything I told you was a lie"
The funny thing about this, is I perpetuated this lie for 2 years(the last part was added on the last month or so, and was only added for sympathy purposes), and actually began to believe it myself, and ended up carving her name in my arm. Good thing it didn't leave a scar, which leads to my other emo moment.
I pretended to be suicidal/that I cut myself for attention, I also wrote horrid poems about how my life sucked, even though my life isn't really bad in any way at all.
EDIT: I was also picked on a lot in school. Seriously, you know that guy who gets picked on by everybody? He even picked on me, and it got worse in High School. One day in class people were throwing shards of a pencil at me when the teacher wasn't in the room. After about 15 or so chunks hitting me, and one nearly hitting my eye, I stand up, flip my desk and yell "I"LL FUCKING KILL YOU, ASSHOLE", and of course, right when I have this outburst the teacher walks in and I'm sent to the guidance office, and get told "Don't shoot up the school"
Another instance, the same fuckers were throwing glass at me on the bus. Seriously, GLASS, broken glass. After the first piece hit me, and I realize what it was, I stood up, had another outburst walked towards the door, and the bus driver told me to sit down. Where I said "Didn't you see him throw fucking glass at me?" The asshole throws ANOTHER piece, and hits me between the eyes, right below my hairline, and I start bleeding. The driver says "No, now sit down", I sat "Fuck you, I'm not riding again", and I push at the door, which the driver is holding close. "Sit down, or I'm getting the principal" He said. Again I say "Fuck you, I'm never riding this bus again", and I kick the bus door, and end up breaking it. (To this day, the door no longer closes)
The next few weeks I walk home, and when the bus would pass me, the same dick, would throw pencils, compasses (circle drawing, not navigation), and a fucking calculator at me. I end up going to the principal, and get taken to a "student court", where I explained my side, and told him watch the buses security tape. The driver lost his job, and I never had a problem with him again, as he was expelled and moved away.
I heard a year later that he hung himself. It's kind of mean to say this, but I don't feel any remorse whatsoever.
