Addicted to picking my scalp

I’ve had this spot that appeared on my scalp about two years ago. It was just a small scab and I picked on it. Then it would heal, and I would pick the dry skin off again, and it would heal, and I would pick at it again… a repeat cycle that I would do for about 2 years. I would pick at it until all the skin comes off and it would leave my scalp pink. Then it would heal and I would start picking the new skin again. This spot has gotten bigger due to be constantly picking at it. It has left a bald spot and im addicted. I can’t wait to get home everyday just so I can start picking at it again once its heal. I don’t know how to stop. Does anyone know ow exactly what this is? And I can get rid of it?
