What one mistake fucked up your entire life?

I chose the wrong school of my country's version of high school. I hate going there everyday and I don't fit in and only have 2 friends I talk to in the entire school and I don't even like the subjects I'm learning or where my life is heading and what colleges I can apply to when I (hopefully) graduate if I haven't dropped out of school and work as a janitor because I hate it so much. I've had depression for a huge part of my life but now it's worse than it's ever been, I can't sleep and waking up is almost impossible. This by far my worst time of my life so far. The only thing that keeps me going forward is the release of Red Dead Redemption 2 in 16 days and 8 hours. It's all I'm looking forward to in life right now
