Well, good character development is crucial. The characters need to be relatable and have interesting personalities. Also, a unique and engaging plot is a must. Maybe a bit of humor and some heartfelt moments too.
First, set boundaries. Don't let them cross into your personal space or control your life. For example, if they try to interfere with your career choice, firmly say no. Second, avoid getting into their emotional games. Don't respond to their attempts to manipulate you emotionally. And third, seek support from outside the family, like friends or a therapist.
