Do you guys believe in family

Family meaning siblings & parents not husband & your kids. Your family can actually be the ones to hurt you the most & drive you crazy and be soo toxic! I literally feel trapped. My family tries to make it seem like I’m selfish because I don’t live by family first. I live by I love those who love me I live by those who show me they care come first regardless if it’s family or a friend or a boyfriend. Whoever give me that real love comes first. I don’t think I’m selfish for it though because my family is so toxic anyone I vent to tells me I can’t wait for you to get your own place . I don’t feel like I belong and I feel misunderstood . Is it a bad thing to want to cut ties with toxic family members just to have a peace of mind? I’m so miserable in this house everyone is just waiting and wishing on my down fall and try to paint me out to be the bad guy and shame me for my body as well as for loving my boyfriend 😂clearly I am not able to love a man! I’m 18 btw. Not only is my feelings being controlled but so is everything in my life as far as when I can leave my house and return I can go out once a week or sometimes none & im just locked in my room with crazy thoughts . I literally feel alone in a house full of “family” 🤦🏼‍♀️ I get headaches everyday just being around these people
