Is it normal that i rub my fingers against my pillow?
ever since i was born i sucked my thumb, my thumb was like a stress reliever for me. it took away axcity and stress. when i turned the age of around 5 it wasn't really taking away the axcity alone so i started rubbing my two finger against my pillow it had to have a soft pillow case on it for me to do it. Ive been doing it till the age of 13 then i starting like mentally writing someone specific name on my pillow. like id mentally be saying the name of that person in my head while rubbing the letters on my pillow with my fingers. Ive been doing this ever since even though that person that i write there name isn't in my life anymore. its annoying because it causes you to think of that person all the time. i cant stop it now its become a habit and i don't even know how i started doing that i guess finding ways to make the feeling stronger. i cant suck my thumb without doing it or do it without sucking my thumb. i do it because it makes me feel less stressed and relaxed and its an addiction and its hard to quit is this normal?
