For my fingers, I just pick at them because I'm bothered by the bumps of the hard skin that forms after picking at them so I pick at that, forming more of the hard skin etc... It's a vicious cycle of blood and pain my parents are no help. They just tell me to stop but it's not that easy I want to stop but I really don't know how. If I try to play with other things it doesn't work cause when I need something to do with my hands picking is the most convenient and quickest way to do it so it doesn't work any other ideas?
