Can anyone tell me why the hell I want to steal more than anything now?

I used to not even have the urge to steal. I knew it was wrong and I would never think of stealing. Then I started to go shoplifting and it was really fun for me. I would get a rush of adrenaline before I would do it. I wouldn't steal a lot. But I would do it and I enjoyed it. I even did it one time and a few hours later my mom wanted me to go grocery shopping. I went to the store I stole from and felt no shame. In fact, it felt cooler. Then I would start to feel guilty afterwards and vow to never do it again. And then a few days later the urge comes back. I just want to go to the liquor store every time I see it and steal liquor. I know that it's wrong and I know that I'm not even into liquor. I'm 15. I just don't understand why I would want to steal so badly. I'm not gonna lie, It's a lot of fun. I just feel like It's wrong to do. And I know I'll be screwed if I ever get caught. I'm not gonna do it. But I just wonder why I have the urge to go out and steal. I just want to go to the grocery store and take a few things every time. I know that It's wrong and that I shouldn't do it. I don't know what kind of illness this is. Anyways, I'm just going to stop doing it.<br><br>Edit: I don't feel the urge to steal anything in particular. It's literally anything I can get my hands on. I'm not gonna steal anything. I just want to know why I would want to steal. I don't understand why I would want to steal something that I don't ever use. Anyways, I'm not gonna steal. I've been to the liquor store multiple times since I've wrote this. I've had no urge to steal any liquor. And I've been to several other stores. And I've not had the urge to steal. In fact, I forgot that I wrote this post. Anyways, thanks.
