Pondering Plastic Surgery

Lately, out of my insecurities, I have been toying with the idea of doing plastic surgery for my nose.  Yet, at the same time, I am aware that  I want to develop my spiritual life (I have been practicing yoga for 11 years and I’ve been teaching it for the past three years) in more depth.  I am starting to meditate again.  However, being so self-conscious physically (especially as I age) and being drawn to the spiritual life are creating a lot of chaos in my mind as I don’t know what the drive for either is, although obviously the drive to meditate seems to make more sense to me.  Can you let me know what the yoga/ayurveda/ and your perspective is about the subject of changing one’s physical appearance?
Thank you so much for your help.
