Hi Elfgirl, and welcome to the forums. A lot of the time our behavior often comes from our parents. I don't know about these problems being congenital, but are often learned and "seen" all throughout childhood. Like a lot of diseases or illnesses, they may be hidden for quite awhile and surface later on.

Have there been any abuse in your life, mostly in childhood? I know a lot of the time if there has been an individual will start cutting. That's how my cutting started.

Hang in there!
