You said to write something scary
Someone hacked into all of your accounts. They know your social security number, credit card information, debit card pin, every single password you've ever created. They used your social security number to buy a house in Orange County, meaning "you" took out a $600,000 loan in your name. There is no feasible way to pay it back. You tried calling a help line but no one answered, and when you hit the answering machine, it was full.
The people you thought loved you actually don't. They were pretending, because they feel sorry for you. People who you thought respected you just want you for your capacity to listen to their problems. You realize you are deeply alone, on an island of your own making, every decision you've ever made socially has made you an outcast, when you thought you were cool.
Every dream you have ever had has been proven to be impossible. You can't escape your own thoughts, and you hate your own thoughts.
