Aww, poor Kasawa-kun. Gomen-nasai ne. I know how that feels. I went to a different college than the one I do now, and my email account for that college was over thrown by a virus. I lost all my papers, my fanfics, and my homework assignments that I worked at least 3 days on. It really wants to make you strangle somebody doesn't it, but that isn't the way to go.
It seems like it's the end of the world for you, but cheer up. Zettai Daijobu Daioh! (Everything will definately be alright!) Also, remember this, the people down in Texas that were hit by Rita lost their homes and some even lost their family. I'm not going to reprimand you, but this is actually far worse. Also, when I lost the chapters for my fanfics, I forgot almost everything that I typed, so I had to change it around, and in all actuality, the chapter was even better than it was before. If you still need to talk, don't be afraid to PM me. My message box always has enough space for you to send a message!
