How to kick an addiction?

hello, before I tell you my story, please just don't judge me because I didn't mean to start what I did. ok, so in feb., I had some sort of back problem from an accident, so my doctor gave me vicidon. I was only sopposed to take one, but one night I took 4. I liked the kindof high it gave me, so I continued doing that, and I kep getting refils. so my backs fine, and a few weeks ago, my supply of vicidon ran out. I missed the feeling I got, and I serched the cabnets and found some from when my mom had surgery. I took some, and now my mom is kindof suspitous. so, how can I just kick my addiction? I know its bad for me and I really don't want to be a junky my whole life and I really want to stop for my own good, so please help. thanks
