Digging and squeezing wounds

My skin picking is self-destructive and raw. I produce wounds which I open over and over again, keeping some from healing for months. I can "work" on a particular wound for hours at a time, digging in it, pulling out slices of skin with tweezers, squeezing the skin, whiping off the flowing blood every now and then. Needless to say, this will has to stop. Anyone doing something similar?
