My skin is naturally enlarged at each corner of my mouth. One time I bit the skin on my left really hard and I have been biting it for two years. I thought that was why, but after reading this site, I realize it is an extension of some nervous fidgeting I have been doing all my life.
Before that I played with my rings. Once I got a valuable wedding ring, I stopped so I wouldn’t loose it. Before that I would twist and play with my earrings. I stopped wearing them, but I sometimes find myself playing with my naked ear, especially the cartlidge at the top. I like to fold it backward and pop it back. Sick. I know.
I have also been a leg shaker for my entire life and I must move my foot back and forth at night in order to get to sleep. I really just cannot sit still.
I am a very motivated and impatient person. I am wondering of all of this means I have ocd. I never thought I did because I am messy and only selectively a perfectionist.
I am so glad to see that I am not the only biter/fidgeter.
