Cracked Nipples. Help?

All my life I have been extremely insecure about my boobs ๐ŸŠ๐ŸŠ because my nipples didn't look like my sister's or my mom's. By the time I was 10, I refused to let my mom see me topless ๐Ÿšซ I didn't want her to see that there was something wrong. I never really looked into it or did any research as to why until I turned 15, for about a year I thought my nipples were mildly inverted. A month ago I was reading a 'mommy' article (I aspire to be an obstetrician so I'm constantly reading stuff like this) and saw someone mention 'Cracked nipples', I Google imaged a picture and realized that's what I had!!!! But every website I see says that it's a result of breastfeeding ๐Ÿ‘ถ I'm only 17 and they've been this way since I could remember. I feel like I'm back to square one with my insecurities, and they've only gotten worse since I'm at that age where stuff is bound to go down (๐Ÿ‘€๐Ÿ’). Is there any way I can fix them? Am I alone in this? I don't know what to do.

PS. I've always been inlove with body piercings and am so drawn to nipple piercings, but no matter how much I research I'm not sure whether or not it's possible on cracked nipples?
