Is it normal when i run my nails on my top lip.
I have been a life long thumb sucker. Suffering from chronic PTSD from a severely abusive relationship made it impossible to stop. My question is when my thumb is in my mouth or even when it's not and my nails are cold I am compelled to run my cold smooth nails across my top lip. It's a very relaxing and soothing feeling I've done all my life.
