Flight Home for Stepdad's Funeral

For my first semester of college, I was blessed with the opportunity to go abroad. But, as of recent, my step-father has just unexpectedly passed in his sleep. Because it is such short notice, plane tickets are too expensive for me to afford, so I need help. I'm not sure if we'll be able to afford a proper funeral, but I do know that I just need to see him one last time. He was my best friend. The ceremony is supposed to be held on either Thursday (09.19.19) or Friday (09.20.19). I need to be there to see him and say my goodbyes. I haven't seen him since I left for college 3 weeks ago.

I need my family but they're on the other side of the world. Please help in any way. Tickets are becoming more expensive the closer it is to my day of travel. I'm currently trying to situate how I can fly out without missing too many days of my classes.
