Death Note #2

I have been thinking a lot about my own death lately. Like "What if this car just rammed into me?" or "What if I 'accidentally' tripped and fell in front of this car?" It is never about me killing myself, just others killing me. I will sit there sometimes and dream about my death. It scares me, because i know if I don't stop I will die... No one knows about this... I need help even when I'm happy I still think about my death. I have to go now... i will write soon. I am currently shaking... Help Me.
