Should I risk it all for an exciting life?

If you're ok with that fact that you might not succeed, but maybe wait until you're a little older. You should definitely finish high school first; it'll make finding a job a little easier.
If you're going to take such a big risk, you ABSOLUTELY NEED to have a backup plan, actually multiple plans. There's no telling what could happen in the city. There are a lot dangerous people out there that like to pray on young girls like you. So if you decide to go, be very careful.
