The skin picking is related to OCD, while it can cause injury, I don't think it in and of itself is considered truly in the same boat as self harm (ie; cutting, burning, hitting) It has more in common with compulsive hair pulling aka Trichotillomania...

Here is more about it:

Chanel - Thanks for posting that. I thought perhaps that's where my picking and scratching might fit in to what you posted, but it doesn't. Honestly, I was hoping that it had something to do with that as opposed to BPD.

I am not going to get into specifics, but I am not one who goes at skin blemishes or anything. I actually inflict damage and then, once the damage is done, I tend to pick at it so it doesn't heal.

Thank you Chanel that is very interesting. With skin picking I don't even realize I'm doing it until I notice the blood

I started cutting when I was 15 and changed to burning when I was 22.

I definitely have a tendency towards OCD.

For me, self harm always had an emotional component. The skin picking was more of an obsessive thing. I just don't even remember how I figured out how to peel skin off of my toes.

However, when I was 1 + years old, I was picking the fur off of a big stuffed teddy bear and putting it into my ears. My mother would come in to wake me up and I wouldn't hear her. By the time I was four, the bear was 1/3 of the size and totally threadbare.

I started cutting when I was 6, but I only do it rarely. I did it a bit over a year ago and I can't even remember how long ago before that, that I last did it.
I'm bulimic the same way. A few years will go by without it bothering me and then it will just pop up for a week or so and then go away.

Carla - I'm with you on the SI thing. I can go months without doing SI, but I can also go a week. It all depends on what is going on in my life.

I think I started cutting myself when I was about 15 or 16. I haven't cut since I was 21. I used to pull out my hair too. I still bite my lips and the inside of my cheeks. Sometimes when i get really stressed I feel like hurting myself, but I do not want to go down that path. I refuse. When the urge gets strong, I'll hold an ice cube in my hand. The feeling of pain calms me down.
