Symptom or entire disorder?

I'm trying to figure myself out, and currently there are many things I do which are problematic. Stealing is one of them. I'm wondering if its just a symptom of a greater issue, or if I could have a shoplifting addiction.

I'll try to explain as concisely as I can.

When I shoplift it is more out of necessity or because I want something and don't necessarily want to pay for it. If I'm hungry but far away from home I will steal a sandwich or platter. If I am going to a friend's I'll steal us snacks. Sometimes I will steal razors, lotion, shampoo, clothing, school supplies, et al. I used to steal everyday until I noticed that every time I went in a store I would see people sort of hiding behind shelves. I often visited the same store more than once in a week because I was stealing so much-- sometimes twice a day. I don't do it so much anymore, as its become a hassle finding new stores if I need something one day.

Some others here mention feeling guilty. I don't feel guilty when I steal. I don't really feel a need to justify it either, I just don't have money and find it easy enough to steal so I'd rather do that.

You sound like me a year ago. I had no guilt about it. Eventually I became careless and was arrested (twice).

I also can't help but feel that though, in my opinion, there is nothing logically wrong with stealing from large corporations, there is something immoral and dishonest about it nonetheless. At least selfish and decadent, materialist. I think I was possibly taking on a lot of bad karma and it came back to haunt me. I'm not sure. I'm still trying to work it out for myself.
