Addicted to My Cell-Phone

I am addicted to my cell-phone. I am absolutely sure. I take it with me everywhere. Even to the bathroom. It is always in my pocket (I know it's bad to carry cell-phones in a pocket, it might cause cancer, but what if i don't hear it in my purse?).
If I don't hear the familiar melody I feel uncomfortable. Sometimes I hear it when nobody is really calling. I guess I just want to hear it so much.
The most weird thing is that I am not waiting for a person to talk to. I am just waiting for my self-phone to ring. I am addicted to my self-phone.
