Help me pay off for my Leg Surgery

Hi, I am a 16 years old teen boy, who is living in Saudi Arabia. About a year ago I had an accident which rendered my legs troubled I had bone fractures due to which I have to get a leg surgery. I do not have access to a health insurance, and the surgery will cost me about 20,000 dollars. My father drives a taxi, and he can't make enough money to help me. He doesn't know that I am doing this. Please help me out. Thank you
