Yeah, I do, but I think about it all the time. One day one of my co-workers asked me if I ever just wanted to shoot myself (my job is sometimes stressful). I replied, "Yes, every day". But like you, there's really nothing in my life per say, nothing really bad. I have everything I need to live, well, hmm maybe not. I don't know what is wrong with me. But yes, I day dream, or, well, in my case night dream (but not while asleep because I work the graveyard shift) about really bad things. I sit there and think of different things I could say on my death note - not that it would matter.. sigh.. I am miserable. I feel an unexplainable emptiness and loneliness, no words can describe what I feel. Well, good luck to you.
