People describe me as arrogant when they know nothing about me, am I one or not?

[Anonymous]

I'm a 16 year old boy, ever since I think I've hit puberty and since my looks massively changed from what they were before, so much so that when my other relatives saw me... they barely recognized who I was. On first impressions every person will see me as arrogant. Now of course they might not say this right away but on friendships on where I've continued to stay friends with a person and I asked them on how they saw me when they first met me, their response is always the same, an arrogant piece of shit. I suffer from low self esteem and have been since I was very young, at an age where a child shouldn't really look down on himself (5-6 years old) but after I've hit puberty, its like I've become a different person. I get attention from females, but when meeting males I get these rude fucking looks like they wanna bash my head with a glass bottle or something (ofc this doesn't happen every time but its still a problem for me) And the thing is, I'm nice with everyone (not the nice guy). I never take credit I'm not supposed to take, I never offend anyone if they don't offend me first let alone bully them. I have morals and goals. And most importantly I never praise myself but when I do I'm often sarcastic, a thing which most people don't seem to understand nowadays. People tell me that I have an emotionless look on my face, kind of like angry looking for some reason. Now I don't know why this happens, but I think it has to do with how I look. My mom tells me I'm handsome, but I think she does it to make me feel better about myself. Every girl that was interested in me came up to me, I never made the first move. So I think it has to do definitely with how I look. I try to be nice, but I'm never an ass kisser. And no by what I said I am not "glamourising myself by talking so much about me" I want to give a clear description on what could possibly be the case for what's been happening to me.

If that many people do then trust them that you are...

wait i forgot to mention, people who are like 5-10 years older than me or even older see me as normal and sometimes even charming as I've had this teacher who barely knew me and favoured me more than her other student, its just that people my age tend to think that, are they still right?

People your age are notoriously immature. I would not care what they thought actually. Keep being you with a calm gentleness, positive vibe, and smile. They will see the good in you as the Elders do or they will not. Do your thing !!
