I don't know if there is really any name for this problem besides anxiety, but I have had this problem since I could remember. Basically, all I can think of is death, and dying. I haven't confided in anyone about this, in fear of what people may think of me. Any situation I think of ends in death. I I leave the house, and 50 various situations run through my mind. I think of what can happen to me as I drive away. I think of what can happen to my parents while I'm gone. I don't even know how to describe what I think of really. My mind just always wonders. I dream of people breaking into my house, and killing me (not all the time, that was just an example of what I see). Every situation I think of ends in tragedy. Typing this makes me feel like a psycho. I have obviously come to terms with the fact that I will die, and all that. I am 18, and just worry constantly. Anyways, perhaps others know what this feels like and can help? I don't want to think like this anymore... as I am constantly scaring myself.
