One of my family members and I got into a fight and they called me dumb and said "I will never get no where in life" and advice?

So they were angry and the basically told me that I was dumb and I was useless and how I would never get no where in life. I knew she meant what she said cause it was said out of anger. Keep in mind this family member was considered that smart one. Was salutatorian in highschool, got high honors in college and she has a superior attitude. It hurts because as I replayed what she said , it tore more heart up even more and I can't stop crying. This really damaged me. Any advice?
