I'm Paranoid!!!!! seriously i am...

So i think I'm paranoid. I keep seeing my friends and family dead on the floor. It feels like I could have been the one to save their lives, but I wasn't there in enough time or couldn't find them. I have dreams like this, but those are just dreams. When I see it during the day it freaks me out. Like one Sunday Josh Pityer left during the service. It didn't bother me until he was gone for 20 minutes. I turned around and saw his family sitting there so he hadn't left with them. I had these flashes of him on the hallway floor unconscious, or so hurt he couldn't get help. My heart started racing and the images ran faster through my mind.I finally got up to go to the bathroom. I walked onto the foyer and there he was sitting on a chair, perfectly fine. This happens to me all the time at school. I keep expecting someone to come down to my classroom and tell me that Laura or Kalie or Kaila or someone from my family are dead or in the hospital. Now I can't get a hold of my dad on his cell phone and I'm picturing him hurt or even worse dead. my heart starts racing and I think about it every second that I don't see him. When i finally hear his voice I will be perfectly fine. But while I don't know where he is I start to cry because of the images, then I get annoyed because I know he's fine and I shouldn't worry, and then I get mad. when he gets home I'll probably hug him and then yell at him for not answering his stupid phone. Now you're probably thinking I'm crazy, but I'm not. I'm just writing this so i can keep my mind focused so i don't worry as much.
