I had my dermatologist appointment today, and it went great! I received nothing but good news, and the doctor said I had nothing to worry about, and probably will not ever develop melanoma. The mole in question is apparently a common thing that does not have anything to do with skin cancer. He did recommend that I go in for yearly checks and keep an eye on things, which I definitely plan to do.
Thank you guys so much for being supportive and easing my mind. I have been able to keep my mind off of things for the past week and stay relatively level-headed. Y'all really helped me a lot.
