I am way addicted. One time I lost the Internet and I was crying for days. I killed my social life in favour of my Internet friends, but I don't regret that. I tend to go pretty mental-case-ish when I'm deprived of the Internet, like right now, and I find myself pretty moody and depressed. I think all of the time about the 'net, and that's not an exaggeration. I think in Internet smilies and I say the word "pwn". As you may know, Kylie's not my real name, but I'm so used to being online I think of myself as Kylie and I have to stop myself from answering to the name. Oh, what do I do? XD I use LiveJournal, Gaia, MSN, and PC mainly. ^o^
I was suicidal one time I didn't have even the computer for two weeks, but that was probably a combination of my depressive and melodramatic streaks.
