TW CANCER 

Yesterday I saw a tiktok about a woman who didn’t get a mole checked out when she was having symptoms of melanoma and now she has terminal stage IV melanoma. I have health anxiety so this really freaked me out and I started fixating on a pretty big mole on my foot that I’ve had my whole life. I also started feeling for swollen lymph nodes and I noticed I can feel one in my groin area and a couple on my neck. Is this normal? I am thin and I read thin people can feel them sometimes but I’m really freaking out. Help please.
