Help! Stranded in Jamaica

My name is Michael and I am from Austria. I am 20 years old and right now I am stuck in Jamaica. In my freetime I do Parkour and Freerunning that includes flips, moving and jumping around. I planed on staying at a friends house in Jamaica, but now he doesn't answer my calls or messages. I met him in an Hostel in Puerto Rico. I already booked my flight back to Puerto Rico and back home. I would just sleep in my hammock but everybody here says it is too dangerous. That's why I need your help to get enough money to be able to stay at the cheapest hostel for the time here.

THANK YOU.
