This Pain Can Go To Hell

I was a school girl who reincarnated into a baby in a fantasy world, but in this new body, there's a terrible pain that I always felt. The pain can only be distracted by some methods like causing other pain on my body. "Camellia, why are your body full of scars?" .... "It's either mental problems or a demonic teachings." .... "Is that the ghost? She's so pitiful." .... I don't know what happened, but I don't want anyone to disturb my perfect hikikomori life in this forest.
