Help Me Get A Flight Back Home

Hi everyone, I’m Ashley so I would like to explain my current situation & the reason I need to reach to everyone for some help. So I bought a ticket yesterday with the hopes of meeting Selena yesterday & I missed my first flight I was so nervous about how I would attend the Iheartradio album release party & I really wanted to go. Additionally what I did was I bought another plane ticket because my first ticket was not refundable. I do not like to ever ask anyone for money but I am currently struggling to go back home :( I spent a little over 500 just trying to come to this event and no I do not have money for another plane ticket. Please if anyone can help I will gladly appreciate it!
