get a nose job

I realllly want a nose job. I don’t think im bad looking but I dont think I’m that opretty either. I think it’s my nose that brings my self esteem down so I know if I got one I’d look a lott prettier and actually be more confident with myself. I most probably will get one this summer with my sistr but I’m realllllly scared. What if it doesn’t come out right? What if I don’tlike it? Will it hurt? Someone tell me how it is.
