Can I get rhinoplasty or another type of surgery for my nose as it is really wide and I constantly get bullied because of it which affects my self confidence?
Bismihi ta'ala
Yes, you can. There is no shar'i problem with that, as long as it does not entail any other form of haram, like non-mahram touching, or, if you are a female, removing of hijab, etc.
Bullies will always bully. If it was not your nose that they wanted to bully about, it would be something else. So your self-confidence should always be high, and this cosmetic surgery could help you, but your spirit must always be strong.
And Allah knows best.
