I'm Ethiopian and I dislike Somalians. How can I change?

This is not meant to offend Somalians or Ethiopians; I just have a major problem and I really need to change. I have such a strong hate towards Somalians and it started when I was a little girl. Where I live, there is many Muslim Somalians and some are very hateful towards Ethiopians (especially Amhara). I'm Oromo, Amhara and Beta Israelian but I never mention that I'm Oromo because Oromo people have a little connection with Somalia (not really). Anywho... I was bullied a lot when I was younger by the Somalian girls because I was Ethiopian. It never bothered me until I was ually aulted by a Somalian man. My hate started to grow and I absolutely cannot control it anymore. I feel disgusted and I feel like a monster; I’m a racist and I really got no idea how to change. I want to learn how to love and not to hate on someone because of their race, religion, etc. After the experience, I just don’t like Somalians and I don’t trust them. How can I change?
