I have mild paranoia. For example when I'm at home, I sometimes get scared over tiny noises and mentally prepare for the worst. 

I get vivid nightmares about someone breaking into my home. I see people close to me get stabbed. 

When taking a walk alone I always look over my shoulder ,expecting to get kidnapped or killed. Sometimes it feels like I'm being stalked. 

I know I sound like some schizophrenic nutcase but I feel like my fear isn't irrational.
Therapy hasn't helped and I generally don't trust people. Thanks for coming to my ted talk.
