I've been picking scabs and my nose since I was a young child.
If something in my nose does not feel "right" I have to feel around to pick it. I cannot tell you how many times I've done this and ended up with a bloody nose or blood on my finger and the mucus. This however is not my most serious problem.
My most serious problem is picking my scabs. I have been treated for anxiety and when I am anxious I feel the need to pick at my scabs to calm myself and make me feel better. Whenever I think about them, have something brush against them or see them (in a mirror or not) I HAVE to pick them. It is in the back of my mind constantly when I do not. I have been known to sit in the bathroom for fifteen to twenty minutes just picking at my arms and legs, and when I am sitting on the computer I pull up my pant legs and pick.
My youth worker has said this could be related to the environment I was raised in: It was very dirty with many fleas that would bite me. I sometimes feel as though they are crawling all over me which causes me to itch and pick at the resulting scratches.
I have asked my family for help to get me therapy or even medication if need be but they tell me it is a "bad habit", not a disorder of any kind. It has had an extremely negative effect on my self-esteem, because once the sores are gone they leave scars. I have not worn shorts, t-shirts or gone swimming in years.
I might not be a severe case as many of you, since I don't pick my face or anywhere on my abdomen, but I would love any sort of advice you could give me.
