Bullying on school excursion

I was bullied by a group of students from other class when I was 14. I was the best student in my class and I went to some geography competitions that made them jealous and provoked bullying. When we went on school excursion, it was 5 worst days in my life. They humiliated me and made fun of me without anyone reacting to it. I was frightened and too weak to stand for myself and I was totally alone, without anyone giving support, compassion or comfort. There was one guy who was the leader of them and he really hated me and he told me that I should be killed. I remember hate in his eyes and those words really wounded me and, as I said, no one gave me support, comfort, compassion which I needed so much. I feel that I would go through that experience much easier if someone supported me. This way I was left alone in my pain and suffering, and that is, believe me, much worse than bullying itself. I was ashamed too much so I didn’t tell anyone about it, until recently.
