Hating family members

My immediate family has always looked over and doubted . This family we’re in always disliked and thought they were better than us . I been accepted in colleges including my dream school & received scholarships. They always talking about I’m not going anywhere because I’m shy and a mama’s girl but honestly I’ve come along way. Them & their kids never went to college and they’re trying to discourage me from going. I’m going to college an 1 hr & 40 mins away and I’m going into the medical field. I’m going to prove them all wrong . All of them have been cut off I’m just tired of this family all I have is my mom,sister, and brother.
