I don't know what to do. :(

I wish I hadn't come to school this early. I could've gotten more sleep if I had stayed for more than 20 minutes in bed. After all, I'm an hour early. Imagine being so depressed and sleepy at the same time. Sounds like hell, doesn't it? It feels like hell, too.
I posted a note on a social networking site He and I shared and tagged him in the note so he'd see my message for him. I did not write the message only for him, but rather, it was a sort-of challenge whether I could post 10 days in a row the corresponding text post for the day. It just so happened that on the first day, I should post "Ten things I want to say to ten different people right now". And he was the first one that came into mind.
I told him almost everything - that I hated not talking to him, I hated him not talking to me, and my intention of fixing things and the reason why I was ignoring him was because I got really pissed-off about our argument.
He didn't comment, reply, or even liked the post. I don't even know whether he read it. :| I really want to talk to him, but i'm scared he's too mad or I had hurt him so much he doesn't want to talk to me anymore. And I don't want to make the first move. It would be as if I can't live without him. Yes, I really can't, but if needed, I must try. :(
But I don't know how. I really don't know how things could and would be back to the way they were before but I wish they still could and would. :(
I really miss laughing with him about things which might not seem funny to others, but to us, it's hysterical. I miss texting with him all day and knowing that he's safe, that he's happy. I miss being the reason for most of his smiles, I miss him telling me he cares. :((
