My bf left me in another state with my son alone...

Hi everyone! 3 days ago I decided to visit my bf who’s in another state with my son who’s not his. But a few minutes ago he decided to leave me after me discovering he’s been cheating on me. He left me in the hotel with my son and said id be going to the airport on my own. He literally left me knowing I don’t know this big city. I’ve never been on a uberor lyft or taxi in my entire life. I’m very very scared because my flight is tmwr in the night which is worst because it’s at night. Getting a ride from a stranger terrifies me. I downloaded the app “Lyft” and I’d like to know if this is what’s going to cost me to get to the airport?? If anyone knows how to use this app. Id like tips and advice..

Thank you in advance 🙏🏻😓
