Don't say that, I don't want to hear you say that. Everyone deserves the chance to talk about what they're feeling, and you definitely aren't drawing too much attention to yourself. You deserve to be talking about this, and we really all are here for you, even if we can't physically be there. Tell us everything you need to say, I promise you we're all open ears.
And I read your blog, it sounds like such a shitty situation. I hate to hear how much pain you are in, but I'd say to keep crying until you can't cry any more. It releases endorphins, and is partly catharsis. I wish I could offer nuggets of wisdom, but I'd just warn you not to get too stuck in the 'high school is forever' mentality. It hurts today, and it should, but try and remember that it's not forever. Don't go making decisions that will effect forever.
It will get better in time, and I know that sounds so stupid, but I promise that it will. Let it hurt for now, but try and find a way to purge those feelings (and I think your writing is doing that). Get it all out of you, and then come back in the morning and look it all over. It might make more sense after some sleep.
