You know you have PTSD when...
-It takes you 15 minutes to mentally prep yourself to drive after getting in the car, and you're still convinced that you're going to crash into something/someone even though everybody tells you that you're a really careful driver
-Any time a stranger strikes up conversations with you (such as at school) you're secretly paranoid that they're a cop/secret agent/kidnapper/rapist, even though you know they're just being friendly*
-You think your friends, family, loved ones are all conspiring against you*
Good ol' omen formation..
-Every time you have a nightmare, you obsess over it.. WHAT DOES IT MEAN?! WHAT ARE MY DREAMS TRYING TO TELL ME?
-If a song comes on the radio talking about a break up, your SO will break up with you. If you see the numbers 666, you think you're going to Hell! If you pass a cemetary, EVEN THOUGH YOU PASS IT EVERY DAY, it means you're going to die!*
* - these are mostly when I'm really anxious/triggered.. I don't walk around thinking this way 24/7.. anymore! ;)
