Thank you. This helps a lot. The real reason is that I was scammed by one of my flatmates for 6000 dollars and out of fear I didn't tell my family back home. I just didn't have the money to buy a flight ticket. I was not working anywhere and was surviving off of popcorn and bread for a couple of months until it got too much for me and I came clean to my dad. He was super pissed but booked a flight for me. But I don't have any documentary evidence of all this except the flight ticket in my email.
