I'm thinking of ghosting my parents.
Is there a reason you want to ghost them?
They need to shut up and leave me alone. Don't know know I'm an adult?
People often get frustrated with their parents, but that's not a reason to abandon them. If you leave them and never talk to them again think about how upset they would be. Instead, talk to them and tell them how you are feeling so you can work through this together.
It's fucking dumb to care about them.
If you are having family problems it is good to talk to them or go see a family therapist. I think it could be really beneficial before you decide to leave.
