Someone PLEASE HELP ME? ANYONE WITH KNOWLEDGE OF *SKIN CANCER* please i'm BEGGING YOU.?

At 17 your chances of having skin cancer are slim, so don't freak out just yet. I can think of several other, more plausible, reasons for your lethargy. You say you've seen a dermatologist, it would be worth your while to also speak to a gp if you haven't already.
