I’ve saved up for years to have this surgery but I’m just worried what people will think?
You poor thing OP, you're feeling damned if you do & damned it you don't, aren't you?
Awful to have endured childish bullying for looking different to any 'accepted norm', & well done you for surviving it & deciding how you now want to address the issue.
The thing is ... may I ask what advice or even counselling you have had about your expectations of the effect surgery will actually give you?
For decades now, your life has been blighted by what do people think?, with your focus on feelings of inadequacy for other people's idiotic perceptions & cruel remarks.
Now, however - at the point of what you are sincerely hoping will be a life-changing surgery - look at where your thoughts are still focused: what will people think?
Do you see how it is the same thought process, for both before AND after your proposed surgery?
So I would like to urge you to be very careful about how much you continue allowing an assumption of other people's judgemental nastiness (& yes, there are plenty of those about, but most people are NOT thinking horrible things about you!) to affect YOUR thinking, YOUR wellbeing, YOUR thought processes, & YOUR decisions about what to do to best manage your own spiritual & emotional wellbeing?
I hope you are very careful about not letting anybody else's opinion cloud your own judgement about what you wish to do & - having done it - whether you "should" or "ought" to have been 'allowed' to do it.
You are an adult. It is your decision, your money, your body & your face. Anybody choosing to naysay that can piss off & look after their own body in the manner of their own choosing - yours is your own body, & your own choice to make.
In short - if you go ahead with your procedure, you need to own it - body & soul! If anyone is rude enough to comment, all you need do is shut them down with neutral or warning responses like -
'Yes, I had a little work done, I'm much happier with my nose now'
'Yes, I was fed up with people commenting on it, so I'm sure they'll stop now' [i.e. shut TF up you insensitive plonker]
'Yes, I've been saving for the procedure for a while, so glad to have it out of the way now'
& repeat until the rude sod goes away, or just change the subject if they are people who are being a bit dense rather than actively rude or bullying.
I practice a religion where any cosmetic surgery is not allowed unless necessary
It's necessary. You say so. Your opinion on the matter is perfectly valid - for you. You are not running around telling anyone else to get their nose fixed - by exactly the same logic, nobody else can run around telling you not to. Nobody else is "allowed" to make decisons about your body. Not even if they are using a religion you happen to share as an excuse to beat you up with.
If your religious community cannot put your emotional wellbeing, mental health, & personal autonomy in front of a silly rule that some old man wrote in an old book once, maybe it's time to rethink that community.
It's a larger can of worms that simply having a quick-fix procedure isn't it @hatelivinglikethis? - & I urge you to place as much importance on the internals as the externals of this decision. In the same way as you are taking care to appoint a trusted surgeon with your face - please find the time & money to spend on a trusted therapist to hold your hand as you deal with all the ramifications of your own expectations, other people's bloody stupidity in their reactions to it ... & addressing the dreadful feelings you still must have about your childhood bullying.
A good therapist will help you unpick a lot of this & find a more peaceful resolution within yourself. It is just as important & valid for you to 'fix' this as it is for you to feel you want to 'fix' your nose.
Best of luck - you are doing a brave thing, look after yourself well INSIDE & out, OP
