insecurities... advice?

I am so insecure about my girl parts, my lady bits, etc. whatever you call it, whatever you name it, I'm insecure!! My inner thighs and my actual lady parts are very dark. I am white but they're a very dark color and I'm not sure why. Is this something I can fix. Also out to my "meat curtain" "beef curtain" "drape lip" gals.. I am very insecure about my longer vaginal lips... should I be? Will people actually care? Not sure if this makes a difference but I'm 19
