Make sure you understand why you are unhappy. Then think about what you want to say to your parents. If you don't think you can speak to them at the moment, try writing a letter.

    Try to reach a compromise (和解). Perhaps you and your parents disagree(有分歧) on something. You can keep your disagreement and try your best to accept each other.
