Let me ask you this: how do you feel about your parents and your uncle making their IQ known? I'm not saying their like this, but there are far too many people who wave their IQ around others their whole lives and carry an air of superiority. Regardless, what I'd like to point out is that you knowing your parents' and uncle's IQ is causing you anxiety because you feel you need to measure up and you aren't allowed to know yours. Maybe you feel that yours isn't very high, or that it's higher than average, but less than your parents' or uncle's. Or, maybe it's higher than theirs. This feels unfair to you and, while I don't think knowing your IQ will change your life, you can always get an IQ test via MENSA or through an accredited professional when you're an adult. In the end, IQ is not what carries you through life, but motivation/drive, focus, and Emotional Quotient (EQ) will take you far. More and more workplaces are administering EQ tests to applicants, as they're recognizing its worth. I would recommend working on your EQ. It is a far greater tool in every aspect of life. All the best!
