GROSS TMI

So when I was younger I would PULL skin off my big toe and on my heel ... and this is even more gross.. I would EAT it. DISGUSTING. Since I did that my feet have these thick calluses that are like a pinkish red — brighter than the rest of my foot. I’m gonna insert pictures. I would like help on how to get rid of the calluses and make them less red and thick. It’s so gross.
