The fact that you have some concerns about not being "too free" with money that your parents gave you -- realizing that you did not earn this money and that you therefore have some responsibility to spend it prudently -- shows good character in my mind. There are other kids who act like they have it all coming to them.

A little bit of anxiety about "not doing the wrong thing" can be a good thing.

Although I often see things differently than I'm Suffering, in this case I agree wholeheartedly with what he wrote here:

"Make a pact in your own mind that after school is over and you are working, you will repay them in kind, in your own way, at some future date. Not that you give them every penny you see. But this symbolically will allow you to accept without guilt, but with love and thanks."

Your "repayment" may be to help support your parents when they are older. Or to help support a sibling or other relative. Or if none of that is needed, perhaps to give charity in your parents' name, to honor the opportunities they gave you. Maybe you will help give another student, who does not have family resources, the opportunity to get a good education.

So get the good education your parents have made possible. Go to university. Work hard at your studies so that their money is not wasted. Spend enough money so that your quality of life is acceptable. Live in a decent place. Eat good food. Buy appropriate clothing. Don't feel guilty about any of that. Don't be frivolous with your parents' money -- be respectful of it -- but don't practice unreasonable self denial either. Your parents are probably proud to be able to send you to good schools and afford you a good quality of life. And then, when you have reaped the benefits of your good education, give something back.
