i am so glad i found this!!

I am 19 years old and have been biting my fingernails, chewing my cheeks, clipping skin off my feet and fingers with nail clippers and eating it for several years. I am very thankful to not be alone with this. I feel very self conscious about it. I have told my boyfriend of my clipping habit but left out the creepy eating it part. I really would love to stop hiding behind these problems and stop doing these habits entirely. I do not know what causes me to do any of these things, maybe boredom, maybe anxiety..
