I just found my old account on Gaia online, because one of my friends was stalking me on the internet and alerted me to its existence, which I had previously forgotten about. An excerpt from my journal:
"no subject
well school is getting serious, history i think is going to get better since im now learning new stuff in that subject for the first time in about 3 years. math still stupid; algebra 1's 1st few lessons are lame review. all i gots to say"
And that's not the worst. You should have seen the one about the boys in my class. Or the bug bites. Or being sick on a Monday. How did this twelve-year-old version of me exist? How was I so ignorant of the existence of grammar? What on earth was my mindset? How could I have been so horrible where other people could read it? What gave me the delusion that ANYONE CARED?
I'll never be able to despise middle schoolers with a clear conscience again because of that thing I used to be.
And the worst part is that that account got hacked because I clicked on some sketchy link, and then it was banned. So I can't log on to go delete any of it.
In fact, I'm now afraid to post this journal for fear that I'll come back to it some day and become nauseated by my own existence. Sorry, future me. I hope none of you strangers on the internet actually read this. And to everyone who knew me on here when I was 13, I apologize for everything.
Moral of the story: the past is a scary place.  

I have no idea why I'm trying to fix the problem of scary old journals by making ANOTHER journal that anyone can read. Sorry.
I wonder what manner of horrors I put on my old Neopets account.... And I'm really glad Runescape doesn't keep records.
