picking since i was 2

When I was two years old I had chicken pocks with my cousins. 16 years later I still have the scar on my nose to remind me of the damage I did from picking at it when I was younger. I did gymnastics between the ages of five and ten and had to wear leotards. My legs were covered in scabs and it’s embarrassing to know what others must’ve thought seeing a little girl in a leotard with hideous legs. It used to be just picking scabs on my skin like arms and legs but then when I hit thirteen and started getting a pimple here and there that’s when it got even worse. When I was younger I had such flawless skin and it all crumbled down during the teenage years. To this day I sit in front of the mirror mutilating my face, picking at invisible areas just to see puss come out. It's so relieving to do that and I don't understand why! My parents have seen me pick my face once in a while but they don't know how drastic this problem really is. I haven't told anyone about this problem because I'm too embarrassed to let anyone know. I wish there was a pill or some magic technology that can just magically fix the part of the brain that triggers this.
