I think your way of looking in the mirror is completely misaligned with how others perceive you. There's a tendency in some people there to kind of focus on some part of your body and concentrate all your insecurities towards it.
You might be surprised by a lot of women in Asia actually want to get surgery to make their noses bigger. A lot of Asian women have somewhat flat features on their face with very small noses, like so:
... and they often consider it so much more desirable and glamorous to have a larger nose. So it might be worth a chuckle that what you're insecure about is actually a source of envy and jealousy among many women on the opposite side of the world.
It might also be worth seeing how a lot of Greco-Roman statues of goddesses like Athena featured women with very prominent noses:
... this is significant since a lot of our ideas of beauty are still influenced by these classical images to some degree or another.
It's worth loving your nose and accept the way you are. That's going to boost your attractiveness far more than getting all insecure and shy about something which a lot of people won't even see the same way you do.
Most people have big noses from that side profile. Most of the girls I have dated have had big noses 😂😂😂 Plus you are really young, you are still growing int your body and your facial structure will change 😊
