What should I do my own family doesn't love me?

My own family doesn't love me. Even my sister said my mom doesn't like me and that no one will love me. All of my siblings talk behind my back. They always make fun of me. Laugh and happy when Im sad or crying. Not supportive of me when Im struggling even in college and working. Always calls me stupid. Never helps me when I have problems. I don't know anymore. I just dont feel good enough. The only person who supports me is my friend and Im happy he is always there for me. I don't know what to do. My family are all adult now some are 47 years old and Im the youngest at being 26.
