Terrible breakup. 😔 please help

I just want advice and comforting words. I'm only 16 years old. This boy was my first boyfriend, My first kiss hug holding hands EVERYTHING, my first and only love. I love him with all of my heart. We started dating When I first came to public school 3 years ago when I was 13. I felt something for him I feel ill never feel for anyone else. I'm worried ill never love someone or look at them the way I do him. He was my other half my soul mate everything. He was the only person I hung out with I don't have many girl friends. We had plans for the future and everything. We wanted to be together forever. He treated me like a queen when we were together but suddenly dropped me to take a "break" yet he's dating another girl now without giving me any closure as to if we're truly done forever or not. I'm crying so much, hyperventilating and I feel so sick to my stomach 24/7. Someone please help me. I don't know how to get over him or what to do and I'm so worried I'll never love anyone else again, because all I want is him.Â
