I think everyone seems to think I'm egotistical
What would make you think it's related to that?
I don't know if I really am, but those people make me think of it.
You shouldn't judge yourself based on what others think of you. You should just go about your life being polite and kind to others with no worry.
You don't know anything. It's not like I'm seeking their approval but they let me know how they feel.
I am sorry that you are being judged like that by them. It is not okay for them to do that and you shouldn't think about what they say about you and internalize it.
