Sorry to hear the bad news. I also worked many years as a waiter. I did that as a part time job when i studied. Even if you never studied, you can still have a good future. Find out what your talent is :-). Many succesful people do not have followed any education/study. And youtube is a great teacher as well and its for free :-). I know how you feel, because I have a debt as well. A bigger debt maybe, a loan for my study. And I am working hard now on Steemit to eventually be able to pay off my debt. I wish you all the best, stay strong and find out your hidden talent (s)!
