Nose job question 😥

So to make it short. The only thing i dont like about myself is my nose…. Its sooo big. Yeah i know you have to love yourself and god made you just the way you are but this has made me have anxiety, social anxiety… feeling ugly taking pictures selfies the most… i feel insecure of it 💔😥 i was just wondering if they hurt and how long does it take? Im scared to fall asleep….
