Beautifully Immortal

Ever since I was a baby I was born with this funny looking sign on my arm. My mother never told me what it was. She doesn't want me to find out. Many people have broken into our homes but i don't know why. We keep moving, houses to houses, city to city, state to state. Pretty soon were going to be able to say, "I lived in all 50 states." I was out with an old friend of mine once. I was drinking coffee, until the sign came up in my coffee. I have seen things others weren't able to see. I grew older and got more curious. I was always bullied at school because people thought I was a freak. Every time I want to collapse a disaster always happens. I'm not normal like everyone else. My mother still won't tell me. What is this sign. Why are people after us? I'm only 17, my name is (y/n). My mom is named Karen. We live together, just us. What's wrong with me? Why can't I just be a normal teenage girl...
