Man, that's a great risk! You should have not done it. That money wasn't yours to gamble. That money was intended for you school dude. I wouldn't do it if I was in your place. I abide by the rule gamble only what you can afford to lose. In your case, you had no right to gamble that because you cannot afford to lose that money.
Haha I did that a few years ago when the school but I spend it when approaching the end of the month
because usually I was given money at the beginning of each month so not too disturbing my activities
I also remember some of my friends experienced the same thing with the OP
