I think I have something horrible inside me that sees always the worst or at least the most nauseating possibility.
I always try to imagine the worst case scenario. It is normal for me to imagine someone learning to hate me for example, before they even know anything about me. I know my faults pretty well as there are pretty familiar. When I haven't heard from someone normally, I sometimes fear that they have died or something similarly horrible. When my friend's cat went missing, I automatically thought it might have been hit by a car (it hasn't returned).
I am fucking paranoid, I get to know people on the internet and don't believe them for shit sometimes. I can't trust that they are who they claim to be or anything. I have trust issues irl but they aren't as bad. In FFXI backstabbing and ridiculous shit was too commonplace, had to learn to not trust people online to a degree. There were too many men pretending to be women playing that game lol. I saw some poor saps get fucked over pretty badly.
