Family falling apart

Hi , We are 3 in family. We parents and a middle schooler. Since a few months we don’t talk to each other much even on weekends. Middle schooler is always in room with door shut and partner and I are never in same room at a time. This is happening unconsciously like our energies repel each other. Whenever I want to talk about this or want to do something together, my family isn’t receptive. I am more than often hurled an insult for me weight or just to remind me of my duty of cooking. How can I find happiness
