You are correct to have desires for your future, and congratulations for all your achievement. However, as long as you live under your parents roof, eat their food, sleep in their bed, etc.etc., you obey their rules. With all due respect, it's time for you to get a job and start a life of your own, out of the home, where you can make your own decisions. When you say "your parents won't let me....," you are really saying that you are allowing your parents to control your life and don't seem willing to help yourself. Moving out on your own doesn't have to be an adversarial thing! I believe your parents would want to see you living on your own before they pass, don't you?
