How can I stop cutting?

I've only been cutting for two weeks now, but it seems like I can't stop. For a while I cut both my wrists, but now I just stick to one of them. I know it's bad, but I haven't been able to go more than one day without cutting. My parents have taken all my scissors away from me, so I don't have anything to cut myself with, but somehow I still find something to use. I have started seeing a counselor, unwillingly, but how can I control the urge to cut? And in the meantime, how can I hide the scars?
