Hmerg. From what I understand, kleptomania is quite rare. The definition here didn't fully answer my question, so here we go.
Sometimes I need to take things. Usually not from stores, most often from my school, considering that's where I am most of the time. :| They're not things I actually want, usually just things like doorstops, screws, and light switch plates. I become fixed on one thing. If I don't or can't get it, I become extremely nervous, can't stop thinking about it, ect. An identical item will not do, I need that one. When I get them, I put them in a box in my closet.
