Awww, i'm sorry...but don't be upset about this. she's probablly busy, o maybe her computer is screwing up. it's only been 2 days after all. so i doubt it's something to worry about...but if a week passes & she still hasn't come online, u might wanna send her a message, just 2 say "hi, haven't talked 2 u in a while"...
trust me, i bet this is no big deal...no reason 2 be depressed. smile:)
I am so sorry te miss your best friend so much. I am acutally in the same possison you're at too- I just got insulted da a girl and I am happning to deal with deppresion right now as well.
The only thing I can tell te is do not worry so much. Your best friend has prouably been so busy lately that she hasn't had time to come online any. And the bright side te should look about yourself is that te have pleanty of other good Friends and people to go around and hang out with. I hope everything gets better with te though. :) I wish te the best of luck.
