Why do people call me weird

I dont know why but ever since i turned sixteen people started to call me weird and ajeeb. Nobody had ever called me that before that point of time. And now i am well into my 20s and people still call me that but now it has started to affect me more because i dont even know what i am doing wrong. Like it would make sense if i just fucking knew. Today as well someone called me abnormal and it affected me so much that i wanted to kms. I am just existing and people just call me weird. I sometimes think it is because of my unconventional upbringing and being fatherless but idk this just doesn't feel right
