Question about bullying in my childhood

When I was a child I realized that I was more aware, smarter, and more mature than my classmates, but I was bullied a lot and rejected. I was a good person, I didn't like to fight, I only fought if necessary, if they provoked me... when I was a child I was very different from the others, I was like more intelligent and more mature... I saw children playing childish things... although I was a child I saw them as if they were smaller, more childish, I didn't say anything to them about being childish, I just thought about it, and I realized that they were very stupid and childish... more than anything childish, but they rejected me and bullied me, honestly when they bullied me I thought they were kind of stupid and I didn't understand the need to bully or why? I remember I was a child and I saw the stupid behavior of the children, they gathered in groups but they gathered in groups as if they were superior and they did not let the others enter, it was like a select group among them and I saw them and said what stupid and childish behavior and I was the same age ... the bad thing is that they bullied me and rejected me and that is why I generated shyness because of those idiots, the good thing is that they could not lower my self-esteem with the rest, only socially they affected me, but in the rest they could not affect me I was aware that I was smarter and more mature than them and I simply saw them as fools ... I thought that as a child and I was not conceited I did not like being conceited, being conceited I saw it as stupidity too and somewhat selfish ... and this whole story is real I am not being conceited
