You need to demonstrate maturity

The unfortunate reality is that when your parents are still supporting you, they’re inclined to think of you as a child and want to tell you how to live your life. When you attain a majority age, having your parents to stop treating you like a child can be somewhat complex and it requires patience and careful handling. Although at this age, you are beginning to think better in setting goals for your future, you still have to rely on your parents to achieve those goals. Your target at this time in your life is not to gain overall independence but to obtain some autonomy to get you to the next step of your growth successfully. This is what you need especially now that you’re successfully navigating through adulthood but you have to ask for it with respect. If you feel under treated, draw closer to your parents at convenient moments and explain how you feel about the way they treat you. If possible ask them what you can do to make them support you as mature and worthy of more trust
