Parents have different ways in raising children. If you are not comfortable on how they are treating you at that age, you should request your parents to sit down with you to discuss the issue. They are not aware of your feelings therefore, you have to open up. By doing so, they may admire your self confidence. You have to win their trust in order to let you do some activities that a 22 year-old does within and outside the home. There may be conditions set by your parents but you can try to negotiate for adjustments to certain degrees. I hope that your parents will understand your situation.
