Addiction to Scab Picking??

Hi. 
By the title you can probably tell that I'm kind of addicted to picking my scabs. 
Whenever I get one, I have to pick at it. It's gotten really bad. I have so many little scars on my arms, legs, and face. I can't stop, no matter what I try. I bring myself down everyday just by looking at them. My mom keeps telling me how ugly they make me, how disgusting it is. I tell myself every night I won't pick at them the next day, but I end up doing it anyway. I want to stop. 
Is there anything I can do or try to stop picking at them?
