I just read on wikipedia about some habit I have since my childhood. It is called skin picking disorder. It is classified as an impulse control disorder. By the act of picking your skin on your fingers or anywhere else on your body, one feels calmed down, and is in a trance-like situation in which negative consequences are being ignored. During this act one tries to let out stress, boredom, anger, and sadness. After stopping that act, one might feel remorse and shame.
When one doesn’t stop doing this, the development of skin cannot be succesfull which will then lead the wounds to get infected and turn into scars.
One can do a behaviour therapy, or a a HRT (habit reversal therapy) which can be done by the person himself on his own. The first step of this therapy consists of writing about that habit. In the following steps they find some opposite behaviour steps to confront the habit with like making your hands into fists when you bite your finger nails. I am thinking about starting with this by writing it down or something like that.
In my case, I mostly pick the skin on my fingers (on the inside of my thumbs and index finger. When I don’t open my palm, the skin around my nails looks normal. The other fingers are untouched), my lips, and the blisters on my feet and heels. I do it since I was a kid, and I only remember my cousin showing it to me. She doesn’t do it anymore, but she has begun biting her finger nails, and now she sometimes bites her lips. I still do it with my fingers, and added my feet and lips as well. I also often bleed, and then I feel remorseful. It looks ugly, is a waste of time (although I usually do it while I do other things like watching a movie), and can hurt in the end. It can also lead to complications in society. When I had to give a finger print for my passport, I had to push my thumb on a screen. Since I pick my fingers on the inside, I can imagine how odd my finger print looked like. The surprised face of the lady was proof :’D
I don’t remember my psychological state when I was a child, but it is true that I do it more often in stressful situations. I also noticed doing it when I was so angry that I even cried, so in a situation in which both feelings are mixed. I also thought that I do it especially when I don’t feel content with myself.
I’m not sure if I should really consider doing a therapy, since I also think that it is expensive. But maybe writing it down would be a good start.
