Is my Nipple and Areola Repairable? The Obvious Asymmetry Has Affected my Self Esteem a Lot. (photo)

I'm not sure whether my nipple & areola have always looked like this, or if this emerged during puberty. For as long as I can remember, I've been very uncomfortable & disgusted by the deformity. The other breast looks fairly "normal" (more aesthetically pleasing) in comparison. Why would this occur? Which procedures will remedy this & their average cost? The nipple itself if misshapen, much smaller, & split. The areola lacks a defined border & is larger, puffier, & bumpier than the other one.
