Heh, I reread something from a couple years back the other day and it didn't suck. I was shocked. It was actually eerie -- at the time I was, mm, fourteen, no experience with depression as yet.
Still nailed some of the unearthly dissociation-from-self and reasonlessness behind cutting, before I even fuckin started.
It's a little strange with me, though. For about a year after I write something (maybe, sometimes it's shorter) I mostly hate it and can't touch it. Then I grow to like it. I have a pretty steep learning curve that way...
And because people take you more seriously will correct spellings/grammar, it makes you look more intelligent, an people do/will/have used improper spelling/grammar against a person.
