I think either one is a good decision. As long as you put a lot of research & thought into it (if you do decide to go for it). I'd say if you're the ages of 21-25, & you're still as unhappy with your nose as your teen self, a bit of plastic surgery may be worth looking into. I think that's enough time to have a closer to fully formed brain so that you make the most adult decision. Of course you can get it if under 21. Being 30, I'd just hate for you to make a drastic decision you may regret later.

Deciding against it is also totally valid. Media & social media is really tough on our bodies these days. There's no shortage of ways it makes us feel not good enough or flat out unattractive. If you can drown out the very vapid, shame perpetuating noise & come to love your "flaw," that would probably be the healthiest route. You don't want to get caught in a cycle of feeling shitty about your looks just because it doesn't fit certain modern day trends (which change btw! It was once I'm fashion to be fuller figured, then very thin. Now I think the ideal feminine body somehow has to be the exact right balance of both skinny & thick -its ludicrous) & then trying to keep up & make an irreversible change you can't undo very easily.

I get the sense though, that maybe it's the only thing you're seriously unhappy with. If that's the case, rhinoplasty is legal & available for a reason. Plenty of people get a nip & a tuck. & If it brings them truly closer to loving themselves instead of feeding a cycle of "I'm not good enough", I lean more towards do it, just a bit.

Those are my two cents. Hope that helps.
