Hating my Car note

When I was a senior I made a very dumb decision and went to a dealership that sells used cars with my mom. I was so desperate for a car and didn’t want to ride the bus, that I ended up buying a car for $12,000. The car I bought is a 2008 Toyota Camry that had about $100,000 + miles on it and had some interior issues. Over time the interior issues worsened a bit. now I’m 19 and regretting the decision I made since I still owe about $5,169. I wish I would’ve made a smarter decision or just saved.
