I don't think it should be blocked
Let his/her world not be just one of you and everything focuses on you causing you stress, as well as one more person to help you to do what you are not able to do to be with you day and night, to reduce the economic and emotional burden of parents. There's also the fact that blocking such a drastic rejection is not conducive to easing your mental burden. Even if you don't like it, you can understand each other better by communicating than by blocking. And you can feel less self-blame as you grow into an adult who is more understanding of your parents. Many of life's necessities and burdens are not something we can appreciate and understand at a young age, but by the time we're old enough to understand, it's too late to undo some of the things we've been through.
Faced with a difficult thing, in the unilateral self-sacrifice before, first communicate the ideas and difficulties of both sides.
While parents are selfless, but human nature, bear too much pressure, many people will bring the emotions and stress to the child; when parents old and unaccompanied, the emotional outlet object and care of the object of only one person, this is a terrible thing for both sides.
