I agree. Yes your experience came to a sucky halt, but don't forget what you did get out of it.
Its hard, but dont think of it as a failure, atleast you had to guts to try. And there's no absolute that says you may not try again
Sure your folks are frugal, but you could maybe find a part time job while you're back home and offer to cover some of the cost. Or propose a loan agreement, where you get to pay them off for some of the expense....
Please dont fall into the fatalistic trap, you just weren't ready for this endeavour right now, but who's to say you won't be ready in the near future?
