I had a period where I'd picture myself biting some random person in my field of view so hard in the forehead that the skull would split open. Pretty sick, yet I never really worried about it (and never told anyone, just coming out now). Thoughts like "I could drive my entire family and me off this cliff" do instill some fear, actually I'm happy that it does. When I was about 18 (I'm twice that now) I pretty much figured emotions were undependable, rudimentary things we once needed to function. I don't think that anymore, still it is nice to feel bad at the thought of loosing one's family. I may have issues, don't I...
